The BTS 5434G is a four-channel, 60 mΩ automotive smart high-side power switch.
The BTS5434G is a four‑channel high‑side power switch in a P‑DSO‑28‑19 package that integrates protective functions such as overload, reverse‑polarity, over‑voltage, and thermal shutdown. 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 load‑current sense signals, allowing precise monitoring of each channel. Pin assignments, electrical characteristics, and protection features are detailed for designers targeting automotive or industrial applications.
