Smart High-Side Power Switch
BTS 5235L
Protective Functions
• Reverse battery protection without external components
• Short circuit protection
• Overload protection
• Multi-step current limitation
• Thermal shutdown with restart
• Thermal restart at reduced current limitation
• Over voltage 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
