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
