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
