Product Summary

The BTS 6123P is a one channel high-side power switch in P-TO-220-7-230 package providing embedded protective functions including ReverSave™.

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.

Basic Features

• Very low standby current

• Current controlled input pin

• Improved electromagnetic compatibility (EMC)

• Fast demagnetization of inductive loads

Protective Functions

• ReverSave™, channel switches on in case of reverse polarity

• Reverse battery protection without external components

• Short circuit protection with latch

• Over-load protection

• Multi-step current limitation

• Thermal shutdown with restart

• Over-voltage protection (including load dump)

• Loss of ground protection

• Loss of Vbb protection (with external diode for charged inductive loads)

• Electrostatic discharge protection (ESD)

Diagnostic Functions

• Proportional load current sense (with defined fault signal in case of overload operation, over temperature shutdown and/or short circuit shutdown)

• Open load detection in ON-state by load current sense

Applications

• µC compatible high-side power switch with diagnostic feedback for 12 V grounded loads

• All types of resistive, inductive and capacitive loads

• Most suitable for loads with high inrush currents, so as lamps

• Replaces electromechanical relays, fuses and discrete circuits
