Product Summary

The BTS443P is an N channel vertical power FET with charge pump, current controlled input and diagnostic feedback with load current sense, integrated in Smart SIPMOS chip on chip technology. Providing embedded protective functions. It is widely applied in the following aspects: power switch with current sense diagnostic feedback for 12V and 24 V DC grounded loads; all types of resistive, capacitive and inductive loads (no PWM with inductive loads); replaces electromechanical relays, fuses and discrete circuits.
