製品概要
概要
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.
