Overview

The TPS4812Q1EVM allows reference circuit evaluation of TI's TPS4812-Q1 smart high-side driver. The TPS4812-Q1 is a 3.5V to 95V smart high-side controller and has two strong 2A gate drivers with separate control inputs allowing multiple configurations including a low power path mode, with auto load wake-up options. The TPS4812-Q1 provides bi-directional current monitoring and adjustable I2t based overcurrent and short circuit protection with configurable auto-retry and latch-off fault behavior.

Features
  • 3V to 80V operating voltage range
  • 16A to 36A adjustable short circuit protection using onboard jumpers
  • Programmable I2t shut down time
  • Programmable short-circuit protection delay
  • Programmable auto-retry and latch options
  • Bi-directional current monitoring
  • LED status indication for fault conditions
