TPS4800-Q1 Evaluation Module for Smart High-Side
Driver
Description
The TPS4800Q1EVM allows reference circuit
evaluation of TI's TPS4800-Q1 smart high-side driver.
The TPS4800-Q1 is a 3.5-V to 80-V smart high-side
controller and has a strong (2-A) gate drive that
enables power switching using parallel MOSFETs
in high current system designs. The TPS4800-Q1
provides adjustable short circuit protection with
configurable auto-retry and latch-off fault behavior.
