This document describes the features and characteristics of Infineon Technologies AG's PROFET® BTS 432 I2 product, including load dump and reverse battery protection, short-circuit protection, current limitation, thermal shutdown, diagnostic feedback, etc.
The PROFET® BTS 432 is a smart high‑side power switch designed for 12 V and 24 V DC grounded loads. It integrates a vertical N‑channel power FET with a charge pump, CMOS‑compatible input and diagnostic feedback, eliminating the need for external components in many applications.
Key features include load‑dump and reverse‑battery protection, over‑ and undervoltage shutdown with hysteresis, short‑circuit protection, ESD protection, and open‑load detection. The datasheet provides pin assignments, maximum ratings, electrical characteristics, protection functions, and package information for designers.
| Supply voltage (Vob) | 63 V |
