BTS 5234L is a smart high-side power switch with two channels and low resistance of 60 mΩ. Suitable for automotive power systems.
The BTS 5234L is a dual‑channel high‑side power switch in a P‑DSO‑12‑2 package, offering low standby current, CMOS‑compatible logic pins, and built‑in protective functions. It integrates an N‑channel vertical MOSFET with a charge pump and provides diagnostic signals via IntelliSense pins.
Key protection functions include reverse battery protection, short‑circuit protection, overload protection, multi‑step current limitation, thermal shutdown/restart, over‑voltage protection, loss‑of‑ground protection, and ESD protection. Diagnostic features give load‑current sense and open‑load detection for both ON and OFF states.
| On‑State resistance RDS(ON) | 60 mΩ |
|---|---|
| Nominal load current (one channel active) IL(nom) | 3.5 A |
| Current limitation IL(LIM) | 23 A |
| Operating voltage Vbb(on) | 4.5‑8 V |
The device is a dual‑channel high‑side power switch.
Input pins accept voltages from –5 V to +10 V, and the sense‑enable pin also operates within –5 V to +10 V.
