  • The L9524C is a control IC for up to six glow plugs of diesel engines. The glow plugs are switched by up to four external PWM-controlled N-channel Power MOSFETs or a single relay in high-side configuration.

    Supply voltage, battery voltage, junction temperature, switches, currents through the glow plugs, and charge pump voltage are monitored.
    A two-wire interface is used to communicate with the diesel engine management system.

    Key Features

    • Active clamping during load dump
    • Charge pump voltage monitoring with shutdown
    • Monitoring of currents through the glow plugs with shutdown at overcurrent (adjustable threshold)
    • Junction temperature monitoring with shutdown
    • Quad gate driver for external N-channel Power MOSFETs in high-side configuration:\t\tGates driven by PWM output signal\t\tAdjustable gate charge/discharge currents\t\tLimited gate-to-source voltages\t\tNegative clamping for inductive loads\t\tAdvanced run-off control\t\tRegulation of the power through the glow plugs\t\t
    • Battery-voltage-compatible two-wire interface
    • Control output for external relay driver
    • Battery voltage monitoring with shutdown
    • Monitoring of external switches
    • Supply voltage monitoring with shutdown
