TPS65313-EVM User’s Guide
The TPS65313-Q1 device is a power management integrated circuit (PMIC) for safety-relevant automotive
applications. This device integrates a wide-input voltage off-battery buck regulator (BUCK1), a low-voltage
buck regulator (BUCK2), and a 5-V boost converter (BOOST). The TPS65313-Q1 device integrates
protection features such as independent voltage monitors, overtemperature protection, watchdog function,
and built-in analog and digital diagnostic tests. The features of the device target safety-relevant
applications with system-safety requirements up to ASIL-C level.
This user's guide provides instructions to power up and evaluate the TPS65313-Q1 device using the
TPS65313-EVM evaluation module (EVM) and software user interface (TPS65313 GUI).
