Smart High-Side Power Switch BTS5246-2L

Overview

Diagnostic Functions
• IntelliSense functionality for each channel
• Proportional load current sense signal by current source
• Open load detection in ON-state by load current sense
• Open load detection in OFF-state by voltage source
• Feedback on over temperature and current limitation in ON-state
• Suppressed thermal toggling of fault signal

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
