PROFET® BTS 432 D2
Smart Highside Power Switch
Features
• Load dump and reverse battery protection1)
• Clamp of negative voltage at output
• Short-circuit protection
• Current limitation
• Thermal shutdown
• Diagnostic feedback
• Open load detection in ON-state
• CMOS compatible input
• Electrostatic discharge (ESD) protection
• Loss of ground and loss of Vbb protection2)
• Overvoltage protection
• Undervoltage and overvoltage shutdown with auto-
restart and hysteresis
Application
• µC compatible power switch with diagnostic feedback
for 12 V and 24 V DC grounded loads
• All types of resistive, inductive and capacitve loads
• Replaces electromechanical relays and discrete
circuits
