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\t Gates driven by PWM output signal\t\t Adjustable gate charge/discharge currents\t\t Limited gate-to-source voltages\t\t Negative clamping for inductive loads\t\t Advanced run-off control\t\t Regulation 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
