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  
SO24  
– 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  
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.  
Junction temperature monitoring with  
shutdown  
Monitoring of currents through the glow plugs  
with shutdown at overcurrent (adjustable  
threshold)  
Supply voltage, battery voltage, junction  
temperature, switches, currents through the glow  
plugs, and charge pump voltage are monitored.  
Monitoring of external switches  
Charge pump voltage monitoring with  
shutdown  
A two-wire interface is used to communicate with  
the diesel engine management system.  
Active clamping during load dump
