L9524C
Glow plug system control IC
Features
■ Quad gate driver for external N-channel Power MOSFETs in high-side configuration: – Gates driven by PWM output signal – Adjustable gate charge/discharge currents – Limited gate-to-source voltages – Negative clamping for inductive loads – Advanced run-off control – Regulation of the power through the glow plugs
■ Control output for external relay driver
■ Battery-voltage-compatible two-wire interface
■ Supply voltage monitoring with shutdown
■ Battery voltage monitoring with shutdown
■ Junction temperature monitoring with shutdown
■ Monitoring of currents through the glow plugs with shutdown at overcurrent (adjustable threshold)
■ Monitoring of external switches
■ Charge pump voltage monitoring with shutdown
■ Active clamping during load dump
