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
