Product Summary

The BTS5231-2GS is a dual channel high-side power switch in PG-DSO-14-31 package providing embedded protective functions.

The power transistor is built by a N-channel vertical power MOSFET with charge pump. The device is monolithically integrated in Smart SIPMOS technology.

Basic Features

• Very low standby current

• 3.3 V and 5 V compatible logic pins

• Improved electromagnetic compatibility (EMC)

• Stable behaviour at undervoltage

• Logic ground independent from load ground

• Secure load turn-off while logic ground disconnected

• Optimized inverse current capability

• Green product (RoHS compliant)

• AEC Qualified

Protective Functions

• Reverse battery protection without external components (GND resistor integrated)

• Short circuit protection

• Overload protection

• Multi-step current limitation

• Thermal shutdown with restart

• Thermal restart at reduced current limitation

• Overvoltage protection without external resistor

• Loss of ground protection

• Electrostatic discharge protection (ESD)

Diagnostic Functions

• Enhanced IntelliSense signal for each channel

• Enable function for diagnosis pins (IS1 and IS2)

• Proportional load current sense signal by current source

• High accuracy of current sense signal at wide load current range

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

• Over load (current limitation) diagnosis in ON-state, signalling by voltage source

• Latched over temperature diagnosis in ON-state, signalling by voltage source

• Open load detection in OFF-state, signalling by voltage source

Applications

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

• All types of resistive, inductive and capacitive loads

• Suitable for loads with high inrush currents, so as lamps

• Suitable for loads with low currents, so as LEDs

• Replaces electromechanical relays, fuses and discrete circuits
