2.4 Recommended Test Procedure
The following test procedure may be useful for evaluating the charger IC outside of a real system
especially when no battery is available to connect to the output (i.e., Load#2).
2.4.1 Maximum Charge Current and Maximum Battery Regulation Voltage in The Safety Limit Register
The Maximum Charge Current and Maximum Battery Regulation Voltage values are stored in the Safety
Limit Register. The Safety Limit Register can only be changed immediately after VBAT>2.5V is attached
or valid VBUS voltage is applied (e.g., POR) but before a change (write command) to any other register. If
the default values (950mA maximum charge current and 4.20V maximum charge voltage) are acceptable
for your application, this step is unnecessary. If not, then the following steps are recommended to reset
the Safety Limit Register.
1. Ensure that Section 2.3 steps are followed.
2. Ensure that PS#1 and Load#2 are off so that all power (VBUS and VBAT) has been removed from the
device. Disconnect Load #2 from the EVM.
3. With the software running, disable (uncheck) the Periodic Resets and Periodic Reads feature and also
disable the Immediate Updates button in the toolbar.
4. For the bq24156A and bq24159EVMs only, ensure that the SLRST pin, connected to JP2, is pulled HI.
5. Turn on PS#1.

6. Use the drop down boxes to select the desired maximum charge current and/or the maximum charge
voltage. The Safety Limit Register in the register bank on the bottom right of the screen will change
color indicating an update is pending. Press the W button next to the register.
7. Re-enable the Periodic Resets, Periodic Reads and Immediate Updates features as previously
recommended.
The Maximum Charge Current and Maximum Battery Regulation Voltages drop down boxes now display
the updated values and the charger is ready for further evaluation. The values remain in the register and
cannot be changed until a POR event.
2.4.2 Charge Voltage and Current Regulation
1. Ensure that the Section 2.3 steps are followed.
2. Turn on Load#2.
3. Turn on PS#1.
4. Software setup:
• Ensure that Immediate Updates is enabled.
• Check Periodic Resets, and set Rate to 1 second (except for bq24157B).
• Check Periodic Reads, and set Rate to 5 seconds.
• Ensure that Rsense is set to 68 mΩ.
• Ensure that Operation Mode is Charger Mode (except for bq24156A and bq24159).
• Uncheck Charge Current Termination if checked.
• Check STAT Pin.
• Select Charge Current Sense Voltage to Normal.
5. Change Charge Current to 950mA and change Input Current Limit to 500mA.
Measure →Ichrg = 650 mA - 850mA
Measure →Iin = 440mA - 500mA
Observe →Diode D1 is on (green)
6. Check Disable Charger. Turn off PS#1, turn off Load #2, and disconnect.
2.4.3 Boost Function for bq24153A, bq24157B and bq24158 Versions Only
1. Adjust PS#1 output to 3.7 V, and disable the output. Connect the PS#1 in series with a current meter
(multimeter) to J2 (BAT+, BAT–). Ensure that a voltage meter is connected across J2 (BAT+, BAT–).
2. Set the Load #1 current to 200 mA ±20 mA, but disable the output. Connect the output of the Load #1
in series with a current meter (multimeter) to J1 (DC+, DC–). Ensure that a voltage meter is connected
across J1 (DC+, DC–). The setup is now like Figure 4 for HPA256.

3. Turn on PS#1 output.
4. Software setup: Change Operation Mode to Boost Mode.
Measure →V(J1(DC+, DC–)) = 5 V ±0.2 V
5. Enable Load #1.
Measure →V(J1(DC+, DC–)) = 5 V ±0.2 V
Measure →Iin = 330 mA ±40 mA
Measure →Io = 200 mA ±20 mA
3 Printed-Circuit Board Layout Guideline
1. To obtain optimal performance, the power input capacitors, connected from input to PGND, must be
placed as close as possible to the integrated circuit (IC).
2. The output inductor must be placed close to the IC and the output capacitor connected between the
inductor and PGND of the IC. The intent is to minimize the current path loop area from the SW pin
through the LC filter and back to the PGND pin. To prevent high-frequency oscillation problems, proper
layout to minimize high-frequency current path loop is critical.
3. The sense resistor must be adjacent to the junction of the inductor and output capacitor. Route the
sense leads connected across the RSNS back to the IC, close to each other (minimize loop area) or
on top of each other on adjacent layers (do not route the sense leads through a high-current path).
4. Place all decoupling capacitors close to their respective IC pin and as close as to PGND (do not place
components such that routing interrupts power stage currents). All small control signals must be routed
away from the high current paths.
5. The PCB must have a ground plane (return) connected directly to the return of all components through
vias (two vias per capacitor for power-stage capacitors, two vias for the IC PGND, one via per
capacitor for small-signal components). A star ground design approach is typically used to keep circuit
block currents isolated (high-power/low-power small-signal) which reduces noise-coupling and ground-
bounce issues. A single ground plane for this design gives good results. No ground-bounce issue
occurs with this small layout and a single ground plane. Having the components segregated minimizes
coupling between signals.
6. The high-current charge paths into VBUS, PMID, and from the SW pins must be sized appropriately for
the maximum charge current in order to avoid voltage drops in these traces. The PGND pins must be
connected to the ground plane to return current through the internal low-side FET.
