Infineon BTS 5234G Smart High-Side Power Switch Datasheet
The BTS 5234G is a dual‑channel high‑side power switch in a P‑DSO‑20‑21 package that integrates protective functions such as reverse‑battery, overload, and over‑voltage protection. It uses a N‑channel vertical MOSFET with a charge pump and CMOS‑compatible logic pins.
Key features include very low standby current, 3.3 V/5 V compatible logic pins, and diagnostic signals (IS1, IS2, SEN) for current‑sense and open‑load detection. The datasheet lists electrical characteristics, pin assignments, and application guidance for resistive, inductive, and capacitive loads.
