BTS5231-2GS

Product Summary

The BTS5231-2GS is a dual channel high-side power switch in PG-DSO-14-31 package providing embedded protective functions. The power transistor is built by a N-channel vertical power MOSFET with charge pump. The device is monolithically integrated in Smart SIPMOS technology. It is suitable for compatible high-side power switch with diagnostic feedback for 12 V grounded loads; all types of resistive, inductive and capacitive loads; loads with high inrush currents, so as lamps; and loads with low currents, so as LEDs. It can also replace electromechanical relays, fuses and discrete circuits.
