1.1 Introduction

The TPSI31PxQ1EVM is an evaluation module (EVM) designed to demonstrate the performance and functionality of the TPSI31P1-Q1 device in a high-side active precharge application, charging a DC-link capacitor. The topology in active precharge is similar to that of a buck converter which uses an inductor in series to limit the charging current rise rate (di/dt) and hysteretic control to control the charging current. The TPSI31P1-Q1 integrates the hysteretic control to fully control precharge without need for external logic.

This user's guide provides connectors, test point descriptions, schematic, bill of materials, and board layout of the EVM.
