TITPS65381EVM
Overview
The TPS65381EVM is an evaluation module designed to demonstrate the capabilities of the TPS65381-Q1, a multi-rail power management unit tailored for safety-critical automotive applications. The board provides a platform to test the integrated buck/boost pre-regulator and multiple linear regulators that support high-temperature operation up to 150 degrees C. It features built-in self-test (BIST) and monitoring functions required for functional safety systems.
Why Choose This Part
The board demonstrates a wide input voltage range of 5.8V to 36V, making it suitable for automotive transients and 12V/24V systems. It highlights the IC's extensive diagnostic features, including an MCU watchdog and error-signal monitoring, controlled via a standard SPI interface.
Applications
Key Specifications
Getting Started
To evaluate the TPS65381-Q1, connect a DC power supply to the VIN terminals and use an SPI controller or an MCU development kit to configure the internal registers. Engineers should utilize the onboard test points to monitor the 32-pin HTSSOP package's power rails and diagnostic signals during various load conditions.
