Product Summary
The BTS 6123B is a one channel high-side power switch in P-TO-220-7-180 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
