The L9466 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.
The L9466 is an all-silicon voltage regulator intended for use in automotive charging applications, suitable for both air and liquid-cooled generators. It regulates the output of an automotive generator by controlling the field winding current using a variable frequency PWM high-side driver.
Key features include thermal protection, short-circuit protection for the field driver, lamp driver, relay driver, and DF (field monitor) outputs. The device also supports single-phase autostart and load response control to optimize performance under varying electrical loads.
