L9473

Car alternator voltage regulator

Features

■ For air and liquid cooled applications

■ Ambient air temperature (thermistor)

compensated

■ Special default compensation curve with TS-

terminal open

■ Compensation curve with application specific

resistor on TS

■ Thermal protection

■ Field driver, lamp driver, relay driver, and df

(field monitor) short circuit protected

■ Load response control

■ Single phase autostart

Description

The L9473 is a monolithic multifunction generator

Voltage regulator intended for use in automotive

charging applications.

This All Silicon Voltage Regulator regulates the

output of an automotive generator by controlling

the field winding current by means of a variable

frequency PWM high side driver.
