SPSB0813-TR

SPSB081 Automotive Power Management IC (PMIC)

STMicroelectronics SPSB081 Automotive Power Management IC (PMIC) provides enhanced power management functionality for electronic control modules. These include various standby modes to minimize power consumption with programmable local and remote wake-up capability, LIN (only for SPSB0815 and SPSB0813), and CAN FD physical communication layers. The device has one low-drop voltage regulator to supply the system microcontroller and one voltage tracker to supply external peripheral loads such as sensors. V1 is available with a fixed rail (5V or 3.3V) and V1 overvoltage detection and protection solution, while V2 is a tracker voltage regulator of V1, programmable by SPI with 5V or 3.3V. Moreover, the device features four high-side drivers to supply LEDs and sensors. All outputs are short-circuit (SC) protected and implement open-load diagnosis. The ST standard SPI interface allows control and diagnosis of the device and enables generic software development.
