L9524C - Glow Plug System Controller

STMicroelectronics

Datasheet Details

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.
