L9524C Glow plug system control IC
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
技术特性
- 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
