Device Description
The TLE9261BQXV33 is a monolithic integrated circuit in an exposed pad VQFN-48 (7mm x 7mm) power
package with Lead Tip Inspection (LTI) feature to support Automatic Optical Inspection (AOI).
The device is designed for various CAN automotive applications as main supply for the microcontroller and as
interface for a CAN bus network.
To support these applications, the System Basis Chip (SBC) provides the main functions, such as a 3.3V low-
dropout voltage regulator (LDO) for e.g. a microcontroller supply, another 5V low-dropout voltage regulator
with off-board protection for e.g. sensor supply, another 3.3V/1.8V regulator to drive an external PNP
transistor, which can be used as an independent supply for off-board usage or in load sharing configuration
with the main regulator VCC1, a HS-CAN transceiver supporting CAN FD for data transmission, high-side
switches with embedded protective functions and a 16-bit Serial Peripheral Interface (SPI) to control and
monitor the device. Also implemented are a configurable timeout / window watchdog circuit with a reset
feature, three Fail Outputs and an undervoltage reset feature.
The device offers low-power modes in order to minimize current consumption on applications that are
connected permanently to the battery. A wake-up from the low-power mode is possible via a message on the
buses, via the bi-level sensitive monitoring/wake-up inputs as well as via cyclic wake.
The device is designed to withstand the severe conditions of automotive applications.

3.3 Hints for Unused Pins
It must be ensured that the correct configurations are also selected, i.e. in case functions are not used that
they are disabled via SPI:
• WK1/2/3: connect to GND and disable WK inputs via SPI
• HSx: leave open
• CANH/L, RXDCAN, TXDCAN: leave all pins open
• RO / FOx: leave open
• INT: leave open
• TEST: connect to GND during power-up to activate SBC Development Mode;
connect to VS or leave open for normal user mode operation
• VCC2: leave open and keep disabled
• VCC3: See Chapter 8.5
• VCAN: connect to VCC1
• n.c.: not connected; internally not bonded; connect to GND
•N.U.: Not Used; Used for internal testing purposes only. Do not connect, leave open, i.e. not connected to
any potential on the board. In case N.U. pins are connected on the board an open bridge has to be foreseen
to avoid external disturbances. The bridge can be shorted by a 0 Ωresistance if signal is needed.
3.4 Hints for Alternate Pin Functions
In case of alternate pin functions, selectable via SPI, it must be ensured that the correct configurations are also
selected via SPI, in case it is not done automatically. Please consult the respective chapter. In addition,
following topics shall be considered:
• WK1..2: The pins can be either used as HV wake / voltage monitoring inputs or for a voltage measurement
function (via bit WK_MEAS). In the second case, the WK1..2 pins shall not be used / assigned for any wake
detection nor cyclic sense functionality, i.e. WK1 and WK2 must be disabled in the register WK_CTRL_2 and
the level information is to be ignored in the register WK_LVL_STAT.
• FO2..3: The pins can also be configured as GPIOs in the GPIO_CTRL register. In this case, the pins shall not
be used for any fail output functionality. The default function after Power on Reset (POR) is FOx.

4.2 Functional Range
Note: Within the functional range the IC operates as described in the circuit description. The electrical
characteristics are specified within the conditions given in the related electrical characteristics table.
Device Behavior Outside of Specified Functional Range:
•28V
< VS,func < 40V: Device will still be functional including the state machine; the specified electrical
characteristics might not be ensured anymore. The regulators VCC1/2/3 are working properly, however, a
thermal shutdown might occur due to high power dissipation. HSx switches might be turned OFF depending
on VSHS_OV configurations. The specified SPI communication speed is ensured; the absolute maximum
ratings are not violated, however the device is not intended for continuous operation of VS >28V. The device
operation at high junction temperatures for long periods might reduce the operating life time;
•VCAN < 4.75V: The undervoltage bit VCAN_UV will be set in the SPI register BUS_STAT_1 and the transmitter
will be disabled as long as the UV condition is present;
•5.25V
< VCAN < 5.50V: CAN transceiver still functional. However, the communication might fail due to out-of-
spec operation;
•V
POR,f < VS < 5.5V: Device will still be functional; the specified electrical characteristics might not be ensured
anymore.
– The voltage regulators will enter the low-drop operation mode
(applies for VCC3 only if bit VCC3_VS_ UV_OFF is set),
– A VCC1_UV reset could be triggered depending on the Vrtx settings,
– HSx switch behavior will depend on the respective configuration:
- HS_UV_SD_EN = ‘0’ (default): HSx will be turned OFF for VSHS < VSHS_UV and will stay OFF;
- HS_UV_SD_EN = ‘1’: HSx stays on as long as possible. An unwanted overcurrent shut down may occur.
OC shut down bit set and the respective HSx switch will stay OFF;
– FOx outputs will remain ON if they were enabled before VS > 5.5V,
– The specified SPI communication speed is ensured.

1) If the load current on VCC1 will exceed the configured VCC1 active peak threshold IVCC1,Ipeak1,r or IVCC1,Ipeak2,r,
the current consumption will increase by typ. 2.9mA to ensure optimum dynamic load behavior. Same applies to VCC2. For
VCC3 the current consumption will increase by typ. 1.4mA. See also Chapter 6, Chapter 7, Chapter 8.
2) Not subject to production test, specified by design.
3) Current consumption adders of features defined for SBC Sleep Mode also apply for SBC Stop Mode and vice versa (unless
otherwise specified).

Note: There is no additional current consumption contribution due to PWM generators.
4) No pull-up or pull-down configuration selected.
5) The specified WKx current consumption adder for wake capability applies regardless how many WK inputs are activated.
6) A typ. 75µA / max 125µA (Tj= 85°C) adder applies for every additionally activated HSx switch in SBC Stop Mode;
In SBC Normal Mode every HSx switch consumes the typ. 75µA / max 125µA (Tj= 85°C) without the initial adder because
the biasing is already enabled.
7) HS1 used for cyclic sense, Timer 2, 20ms period, 0.1ms on-time, no load on HS1.
In general the current consumption adder for cyclic sense in SBC Stop Mode can be calculated with below equation:
IStop,CS = 18µA + (525µA *tON/TPer)
8) Also applies to Cyclic Wake

System Features
5 System Features
This chapter describes the system features and behavior of the TLE9261BQXV33:
• State machine
• SBC mode control
• Device configuration
• State of supply and peripherals
• System functions such as cyclic sense or cyclic wake
• Supervision and diagnosis functions
The System Basis Chip (SBC) offers six operating modes:
• SBC Init Mode: Power-up of the device and after a soft reset,
• SBC Normal Mode: The main operating mode of the device,
• SBC Stop Mode: The first-level power saving mode with the main voltage regulator VCC1 enabled,
• SBC Sleep Mode: The second-level power saving mode with VCC1 disabled,
• SBC Restart Mode: An intermediate mode after a wake event from SBC Sleep or Fail-Safe Mode or after a
failure (e.g. WD failure, VCC1 undervoltage reset) to bring the microcontroller into a defined state via a reset.
Once the failure condition is not present anymore the device will automatically change to SBC Normal Mode
after a delay time (tRD1).
• SBC Fail-Safe Mode: A safe-state mode after critical failures (e.g. WD failure, VCC1 undervoltage reset) to
bring the system into a safe state and to ensure a proper restart of the system. VCC1 is disabled. It is a
permanent state until either a wake event (via CAN or WKx) occurs or the overtemperature condition is not
present anymore.
A special mode, called SBC Development Mode, is available during software development or debugging of the
system. All above mentioned operating modes can be accessed in this mode. However, the watchdog counter
is stopped and does not need to be triggered. This mode can be accessed by setting the TEST pin to GND
during SBC Init Mode.
The device can be configured via hardware (external component) to determine the device behavior after a
watchdog trigger failure. See Chapter 5.1.1 for further information.
The System Basis Chip is controlled via a 16-bit SPI interface. A detailed description can be found in
Chapter 15.The configuration as well as the diagnosis is handled via the SPI. The SPI mapping of the
TLE9261BQXV33 is compatible to other devices of the TLE926x and TLE927x families.
