STMicroelectronics Power Management - Specialized L9916BBDTR

The L9916BBDTR is an automotive multifunction alternator voltage regulator designed for 12 V and 24 V onboard networks. It is AEC-Q100 qualified and features a fully monolithic design, high side field driver, and a self-start function. The device includes a thermally compensated regulated voltage and allows for configurable parameters through one-time programmable (OTP) cells, making it suitable for a variety of charging applications. Key functionalities include a lamp driver for wake-up and warning detection, load response control (LRC), and a voltage control loop that can be configured for either proportional-integral or proportional-only control. The L9916BBDTR also incorporates several protection features, including thermal shutdown and field short circuit protection, ensuring reliable operation in automotive environments. This product is available as a bare die, which may be advantageous for specific integration requirements in custom applications.
