SLVSDJ1A July 2016 – May 2017 TPS65381A-Q1
The TPS65381A-Q1 device is designed to operate using an input supply voltage range from 5.8 V to 36 V (CAN, I/O, MCU core, and functional sensor-supply regulators) or 4.5 V to 5.8 V (3.3-V I/O and functional MCU-core voltage). The device has two supply pins: VBATP and VBAT_SAFING. The VBATP pin is the main supply pin for the device. The VBAT_SAFING supply pin is for monitoring (VMON) and BG2 functions. Both the VBATP and VBAT_SAFING supplies must be reverse protected. The VBAT_SAFING pin should be connected to the VBATP pin with a low impedance connection to minimize voltage differences between the device supply pins. For additional power supply recommendations, refer to the TPS65381EVM User's Guide.
