The TPS65381AQDAPRQ1 device is a multirail power supply designed to power microcontrollers (MCUs) in safety-related applications such as the automotive and industrial markets. The device supports Texas Instruments' Hercules™ TMS570 MCU and C2000™ MCU families, as well as various other MCUs with dual-core lockstep (LS) or loosely coupled architecture (LC).

The TPS65381A-Q1 device integrates multiple power rails to power the MCU, Controller Area Network (CAN) or FlexRay, and external sensors. An asynchronous step-down switch-mode power converter with internal FETs converts the input supply (battery) voltage to a 6V pre-regulator output. This 6V pre-regulator powers the other regulators. The device supports wake-up from IGNITION or wake-up from CAN transceiver
