This document describes the features and characteristics of the PROFET BTS 432 F2 smart highside power switch produced by Infineon Technologies AG, including load dump and reverse battery protection, negative voltage clamp at the output, short-circuit protection, current limitation, thermal shutdown, diagnostic feedback, open load detection in ON-state, CMOS compatible input, electrostatic discharge (ESD) protection, loss of ground and loss of Vbb protection, overvoltage protection, and undervoltage and overvoltage shutdown with auto-restart and hysteresis. The product is a microcontroller compatible power switch with diagnostic feedback for 12V and 24V DC grounded loads, most suitable for inductive loads, and can replace electromechanical relays and discrete circuits.
The PROFET® BTS432F2 is a smart high‑side power switch designed for 12 V and 24 V DC grounded loads. It integrates a charge‑pump N‑channel MOSFET with CMOS‑compatible input, offering load‑dump, reverse‑battery, over‑/undervoltage, short‑circuit, and ESD protection, as well as diagnostic feedback such as open‑load detection.
The document provides pin definitions, maximum ratings, electrical characteristics, protection functions, truth tables, and package information for the TO‑220AB/5 and SMD versions, enabling designers to replace electromechanical relays with a fully protected semiconductor solution.
