SPSB100BTR

SPSB100BTR is a fully integrated automotive power management system IC, especially designed for highly integrated application processors (for example, Stellar G and P MCU families), offering low power mode and high current capability. This device comes with enhanced system power supply functionality. It combines a 3-switch mode power supply together with two integrated linear voltage regulators. The device integrates a further 2 wake-up inputs and advanced fail-safe functionalities. The boost controller is intended only to sustain cold cranking pulses, start stop and weak battery conditions for a transitory time. Different combinations enable to supply the system microcontroller, external peripheral loads and sensors in several and adjustable voltage and current ranges. The ST standard SPI interface allows control and diagnosis of the device and enables generic software development.
