The power transistor is built by a N-channel vertical power MOSFET with charge pump. The design is based on Smart SIPMOS chip on chip technology. The BTS50080-1TEA has a current controlled input and offers a diagnostic feedback with load current sense and a defined fault signal in case of overload operation, overtemperature shutdown and/or short circuit shutdown.

It is based on Smart power chip technology with P-channel vertical power MOFSET, providing protective and diagnostic functions. It is especially designed to drive loads in the harsh automotive environment.
