1 / 27 page  January 2008 Rev 3 1/27 1 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 Description 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. SO24 Table 1.
