TPS7B4254-Q1 Overview
Description
For automotive off-board sensors and low-current offboard modules, the power supply is through a long cable from the main board. In such cases, protection is required in the power devices for the off-board loads to prevent the onboard components from damage during a short to GND or short to battery caused by a broken cable.
