Smart High-Side Power Switch

BTS50080-1TEA

Overview

Datasheet 4 Rev. 1.0, 2008-08-28

Protective Functions

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

• Reverse battery protection without external components

• Short circuit protection with latch

• Overload protection

• Multi-step current limitation

• Thermal shutdown with restart

• Overvoltage protection (including load dump)

• Loss of ground protection

• Loss of V

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, overtemperature

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
