BTS452TXT

Power Distribution Switches, Load Drivers Overview

The BTS452TXT is a high-side power switch from Infineon's miniPROFET series, designed for automotive applications. It integrates a vertical N-channel power FET with embedded protection and diagnostic functions. The device operates within a load voltage range of 6V to 52V and supports a maximum output current of 1.8A. It features a typical on-resistance of 150 milliohms and includes fixed current limiting, overtemperature, and overvoltage protection with auto-restart capabilities. Qualified under AEC-Q100, it utilizes a PG-TO252-5 surface-mount package.
