L9474N数据手册集成电路（IC）的特殊用途稳压器规格书PDF

描述 Description

The L9474N is a monolithic multifunction generator voltage regulator intended for use in automotive applications.

This device regulates the output of an automotive generator by controlling the field winding current by means of a variable frequency PWM high side driver.

The setpoint voltage reference is selected by the ENGINE CONTROL UNIT via RVC protocol.

特性 Features

• High side field driver
• Thermal protection
• Field driver short circuit protection
• RVC interface
• Overvoltage protection
• Complex diagnostics
• Load Response Control
