产品概述
描述
The SPSB081 is a power management system IC providing electronic control modules with enhanced power management functionality, including various standby modes to minimize the power consumption with programmable local and remote wake-up capability, as well as 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 (5 V or 3.3 V) and V1 overvoltage detection and protection solution, while V2 is a tracker voltage regulator of V1, programmable by SPI with 5 V or 3.3 V. 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.
