TPS65381-Q1 datasheet



The TPS65381-Q1 device is a multi-rail power supply designed to supply microcontrollers in safety applications, such as those found in automotive applications. The device supports Texas Instruments’ TMS570LS series 16- bit or 32-bit RISC flash MCU and other microcontrollers with dual-core lockstep (LS) or loosely-coupled architectures (LC).

The TPS65381 device integrates multiple supply rails to power the MCU, CAN, or FlexRay, and an external sensor. An asynchronous-buck switch-mode power-supply converter with an internal FET converts the input battery voltage to a 6-V pre-regulator output. This 6-V pre-regulator supplies the other regulators.

Furthermore, the device supports wake-up from IGNITION or wake-up from the CAN transceiver.
