The TPS65381QDAPRQ1 from Texas Instruments is a multi-rail power supply IC suitable for microcontrollers in safety-relevant applications. It is designed for automotive and industrial safety environments, operating within a temperature range of -40°C to 125°C.
This IC supports multiple supply rails, including a 6-V asynchronous switch mode preregulator with a 1.3-A output current, a 5-V linear regulator for CAN communication with a 300-mA output, and adjustable 3.3-V or 5-V linear regulators for MCU I/O. The input voltage range is specified from 4.5 V to 40 V, with specific functional ranges for different regulators.
Key features include communication control, power good indication, thermal shutdown, and undervoltage lockout (UVLO). The device is housed in a 32-HTSSOP package and is qualified for automotive applications under AEC-Q100.
Note: This part is not recommended for new designs. An alternate product, TPS65381A-Q1, is available with upgraded functionality.
