Product overview

Description

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.

  • All features

    • AEC-Q100 qualified
    • One 5 V (or 3.3 V for SPSB0813 and SPSB081C3) low drop voltage regulator (V1) for microcontroller and peripheral supply
    • One configurable 5 V or 3.3 V, selectable via SPI, low drop voltage regulator V2 tracker for V1 and with off-board protection
    • Minimum current limitation of 450 mA for V1 and 400 mA for V2
    • No electrolytic capacitor required on regulator outputs
    • Very low quiescent current in standby modes (typ. 15 µA)
    • Programmable reset generator for power-on and undervoltage
    • Configurable window watchdog
    • LIN transceivers ISO 17987-4/2016 compliant (only for SPSB0815 and SPSB0813)
    • CAN-FD transceiver (ISO 11898-2/2016, SAE J2284 compliant) with local failure and bus failure diagnosis
    • Complete 2-channel contact monitoring interface (WU1 and WU2 input pins) with programmable cyclic sense functionality. WU2 also with DIR functionality
    • Programmable periodic system wake-up feature
    • STM standard serial peripheral interface (32Bit/ST-SPI)
    • 4 HS drivers for 0.14 A (RON = 7 Ω) suitable to drive external LED modules with high input capacitance value or to also supply external contacts
    • Internal 10-bit PWM timer for each standalone high-side driver
    • Buffered supply for all voltage regulators
    • DIAGN output pin for fail-safe signalization
    • Current monitor output for all internal high-side drivers
    • Open-load diagnosis for all outputs
    • Overcurrent protection for all outputs
    • V1 overvoltage detection and protection
    • Device contains temperature warning and protection
    • Thermal cluster
    • Limited documentation available for customers that need support when dealing with ASIL requirements as per ISO 26262
