bq24072/3/4/5/9(T) and bq24230/2 1.5-A Single-Chip Li-Ion
and Li-Polymer Charge Management IC EVM
This user’s guide describes the bq24072/3/4/5/9(T) and bq24230/2 (bqTINY-III™) evaluation module
(EVM). The EVM provides a convenient method for evaluating the performance of a charge management
and system power solution for portable applications using the bq24072/3/4/5/9(T) and bq24230/2 product
families. A completely designed and tested module is presented. The charger is designed to deliver up to
1.5 A of continuous current to the system or charger for one-cell Li-ion or Li-polymer applications (see the
data sheet for correct device) using a dc power supply. The charger is programmed from the factory to
deliver 0.9 A of charging current. This EVM was designed as a stand-alone evaluation module, but it also
can be interfaced with the system and host via the connectors and headers.

Charge Management IC EVM
1 Introduction
The bq2407x and bq2432x powers the system while independently charging the battery. This feature
reduces the charge and discharge cycles on the battery, allows for proper charge termination, and allows
the system to run with an absent or defective battery pack. This feature also allows for the system to
instantaneously turn on from an external power source even when using a deeply discharged battery
pack.
This charger has one input and can be programmed to be used with an adapter or USB port as the power
source for the system. In the USB configuration, the host can select from the two preset input maximum
rates of 100 mA and 500 mA. The charger dynamically adjusts the charge rate based on the system load
to stay within the 100-mA or 500-mA maximum limits. An external resistor, RSET1, sets the magnitude of
the charge current. If the charge current exceeds the available input current, the voltage on the OUT pin
drops to the DPPM threshold or the battery voltage, whichever is higher. The charging current is reduced
to what current is available (IBAT = IIN–IOUT).
The integrated circuit (IC) charges the battery in three phases: conditioning, constant current, and
constant voltage. Charge is terminated based on minimum current. A resistor-programmable charge timer
provides a backup safety for charge termination. The charge automatically re-starts if the battery voltage
falls below an internal threshold. Sleep mode is entered when the supply is removed (Vin drops to the
battery voltage).
2 Considerations When Testing and Using bq24072/3/4/5/9(T) and bq24230/2 ICs
Consider the following noteworthy items while testing and using the bq2403x ICs.
The bq24072/3/4/5/9(T) series targets current above a nominal 500 mA (>350 mA) and the difference are
listed in Table 1.

The bq24079(T) ICs are regulated to 4.1 V. The "T" version uses a voltage-based TS bias, which allows
more flexibility in setting the temperature range, whereas the bq24072/3/4/5 ICs use current-biased TS.
The bq24230/2 family is identical to the bq24073/4 ICs except that they are trimmed and their target
current values nominally are at 300 mA (<450 mA). This family is suited for headset designs. The pinout of
each IC is the same across both families except pin 15 (JMP2 on the EVM); the pin 15 function is listed in
Table 1 under the Optional Function column.

bq24072/3/4/5/9(T) and bq24230/2 1.5-A Single-Chip Li-Ion and Li-Polymer
Charge Management IC EVM
The two potential sources to power the system (VOUT) are the input source and the battery (adapter or
USB port). The IC is designed to power the system continuously. The battery, in most cases, is the last
line of backup. If the adapter/USB input is not available (or disabled), the battery connects to the system.
In thermal regulation condition (TJ= 125°C not a first-choice design mode of operation), the charge current
is reduced to the battery, and the system still gets its power from the input. The battery supplement is
available in thermal regulation if the VOUT falls to VBAT. In thermal cutoff (~155°C), the input sources are
disconnected, but the internal battery FET connects the battery to VOUT.
3 Performance Specification Summary
Table 2 summarizes the performance specifications of the EVM.
(1) The HPA073 (bq24072/3/4/5/9(T) and bq24230/2) thermal design is optimized (8+vias, 0.031-inch PCB, 2-oz. copper) to give
θJA ~ 27°C/W.

3.1 Performance Recommendations
This IC is a linear battery charger and also powers the system from the input via the linear regulator
output. The key here is that this is a linear device that is most efficient when the input voltage is not too far
above the battery voltage (Vin = 4.75 V to 5.5 V). Too low of input voltage (less than the OUT voltage plus
the dropout voltage) results in degraded performance. Excessive input voltage (>5.5 V) results in excess
power dissipation and reduced performance via thermal regulation. The IC is rated to 28 V, and will not be
damaged with Vin voltages less than this, but any Vin voltage over the overvoltage protection (OVP)
threshold disables the IC. Thus, the recommended operating range for maximum performance is between
4.75 V and 5.5 V, with a preference toward the lower values.

4.3 Test Procedure
1. Verify that the equipment and EVM is set up according to the preceding section.
2. Verify that VOUT is approximately equal to VBAT
3. Turn on P/S#1, +5.25-Vdc supply to the UUT.
4. Verify VBAT is between 2.4 Vdc and 3 Vdc, and the charger is in precharge state: LEDs CHG (D1) and
PGOOD (D2) are on. If VBAT is above the low-voltage threshold (V(LOWV) ~3 V), then the IC is in fast-
charge mode. If the IC is in fast charge, skip step 7.
5. Verify DMM#3, IBAT is ~9 mV or ~0.09 A
6. Verify that VOUT for bq24072 is ~200 mV above the battery voltage or a minimum of 3.4 Vdc. For
bq24073/4 verify that VOUT is ~4.4 Vdc. Verify that bq24075/9(T) is ~5.5 Vdc for VIN > 5.6 V and equal
to VIN for Vin < 5.6 V.
7. Allow the battery to charge until VBAT is between 3.3 Vdc and 4 Vdc. The charger delivers the
programmed constant current to the battery unless the input cannot source the required current.
8. Verify IBAT is ~88 mV or ~0.9 A (for a 1-kΩresistor on ISET).
9. Verify VOUT : bq24072 – ~200 mV above the battery voltage.
10. Set JMP5 (EN1) to HI, and verify that the chip has been disabled, D1 (CHG) has turned off, and the
P/S#1 current has dropped to zero. The internal battery FET must be on, connecting the BAT pin to
the OUT pin. Verify that the voltage on the OUT pin is close to the battery voltage. See Figure 2 for
EN1/2 modes of operation.
11. SET JMP4 (EN2) to VSS. Verify that the input current is less than 500 mA (USB 500-mA mode). If the
input current is restricted due to USB mode, or if the adapter is current limiting, the OUT pin drops in
voltage and enters the DPM mode, if the system current is less than the restricted input current. This
IC must be in DPM mode with the system voltage at the DPM
12. Set JMP5 (EN1) to VSS and verify USB 100-mA mode. The system load is more than the allowed 100
mA on the input, so the OUT voltage drops to the battery voltage, and the battery FET is switched on

and supplements the input current. Verify that Vout has dropped just below the battery voltage and the
battery is supplying Ibat, ~(Vout/10 Ω– 100 mA).
13. Set JMP4 (EN2) to HI to return to the ISET mode where the programmed current is ~0.9 A.
14. Set JMP3 to HI, and verify that the charging is disabled and that the CHG LED (D1) turns off. Verify
that the system is still powered by the input. See Figure 3.
15. Set JMP3 to VSS, and verify that charging continues and that D1 turn on.
16. Record the OUT voltage and battery charge current. Adjust R8 CCW until the input current starts to be
reduced (~2 turns). Note how the OUT voltage drops and the charge current is reduced as the input
current limit loops kicks in and limits the input current. Adjust R8 to its original position
17. On the bq24075 IC, set JMP2 HI, and verify that the BAT FET turns off and allows no charging or
discharging of the battery.
18. Adjust the R16 (TS-Pot) up or down until the TS threshold is reached. Verify that the charging current
is disabled. Return the TS resistance within the normal range and verify the continued charging
operation.
19. Allow the battery to continue to charge until the battery reaches voltage regulation, ~4.2 V ±40 mV for
bq24072/3/4/5/9(T) and 4.1 V ±4 mV for bq24079(T). Verify that the voltage is regulated as the current
tapers over the next one-to-two hours depending on the battery capacity. See Figure 4 for a charge
profile (time in plot is not proportional to actual charge time).
20. Verify that the current tapers to around 90 mA (9 mV on DMM#3) when termination occurs. Note on
the ’72 and ’73 ICs that termination can be disabled by setting the TD pin HI (JMP2). Also note that on
’74, the ITERM resistor (R10) can adjust the termination threshold.
21. Verify that the LED, D1, turns off and the current drops to zero.
22. Turn off P/S#1, and allow the system load to discharge the battery until a refresh charge is initiated.
Verify that the battery voltage dropped to ~4.1 V for bq24072/3/4/5 and to 4.0 V for bq24079(T) prior to
refresh.
23. Verify that the LED, D1, did not turn on for the refresh cycle.
This concludes the procedure for demonstrating the features of this power path charger. See the data
sheet for more detailed explanations and instructive waveforms.

to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by
neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have
been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications
or instructions for such EVMs or improper sytem design, or (c) User has not paid on time. Testing and other quality control
techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.
User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10)
business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected.
2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit
User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty
period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or
replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be
warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.

FCC Interference Statement for Class A EVM devices
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.

FCC Interference Statement for Class B EVM devices
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
3.2 Canada
3.2.1 For EVMs issued with an Industry Canada Certificate of Conformance to RSS-210
Concerning EVMs Including Radio Transmitters:
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:
(1) this device may not cause interference, and (2) this device must accept any interference, including interference that may
cause undesired operation of the device.
Concernant les EVMs avec appareils radio:
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation
