BTS50080-1TMA
Overview
Datasheet 4 Rev. 1.0, 2008-01-23
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 V
bb
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
