1 Introduction

The TPS48111Q1EVM allows reference circuit evaluation of TI's smart high-side driver TPS48111-Q1. The TPS48111-Q1 has an operating range of 3.5 V–80 V and has strong gate drive strength of 4 A to enable switching parallel MOSFETs in high current designs. The controller TPS48111-Q1 can drive back-to-back N-channel MOSFETs and also has a separate pre-charge driver (G) with independent control input (INP_G) to drive large capacitive loads. The device provides two-level adjustable overcurrent protection with adjustable circuit breaker timer, fast short-circuit protection, accurate analog current monitor output, and remote overtemperature protection.
