The BTS50080-1TEA is a one channel high-side power switch in PG-TO252-5-11 package providing embedded
protective functions.
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.

Smart High-Side Power Switch
BTS50080-1TEA
Overview
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 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, 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
