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
