L9915 - C-terminal alternator voltage regulator

General Description

The device is a monolithic alternator voltage regulator intended for use in automotive application.

It includes the control section, the field power stage, fault diagnostic circuit which drives a warning lamp, and the protection against short circuits.

Key Features

  • Fully monolithic design.
  • High side field driver.
  • Field short circuit protection.
  • Regulated voltage driven by ECU (protocol driven).
  • Regulated voltage thermally compensated (without protocol).
  • Lamp driver (wake up and warning detection).
  • Self start function.
  • Load response control (LRC).
  • Field monitor (FM) output.
  • Thermal shutdown.
