L9524C Datasheet (ST Microelectronics) - Glow Plug System Controller

L9524C, Glow Plug System Controller

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.
