The PROFET® BTS 432 E2 is a high side power switch produced by Texas Instruments. It has negative voltage output clamping, short circuit protection, current limiting, thermal shutdown, diagnostic feedback, open load detection, CMOS compatible input, electrostatic discharge (ESD) protection, power ground and Vbb protection, overvoltage protection, undervoltage and overvoltage shutdown. It can be compatible with 12V and 24V DC grounded loads of microcontrollers, and can replace electromechanical relays and discrete circuits.
The PROFET® BTS 432 E2 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 charge‑pump technology, CMOS‑compatible input, and extensive diagnostic feedback, allowing it to replace electromechanical relays in resistive, inductive, and capacitive applications.
Key specifications include a supply voltage rating of 63 V, load‑dump protection up to 66.5 V, on‑state resistance as low as 30 mΩ, and a power dissipation capability of 125 W. The device also features multiple protection functions such as short‑circuit, over‑voltage, under‑voltage, reverse‑battery, and ESD protection, making it suitable for a wide range of industrial and automotive power‑switching tasks.
