The BTS 5434G is a four-channel, 60mΩ automotive power smart high-side power switch.
The BTS 5434G is a four‑channel high‑side power switch in a P‑DSO‑28‑19 package that integrates protective functions such as overload, reverse‑polarity, and over‑voltage protection. It uses an N‑channel vertical power MOSFET with a charge pump and provides CMOS‑compatible logic inputs.
The device offers diagnostic feedback via IntelliSense pins, sense‑enable pins, and separate output pins for each channel. Pin configuration, electrical characteristics, and protection features are listed in detail, making it suitable for automotive and industrial load control applications.
