    Key features
    Key features
    • AEC-Q100 grade 1 qualified
    • Two configurable (6.5 V, 5 V, 3.3 V) buck converters (up to 3.0 A ) @ 2.4 MHz or 400 kHz
    • One buck converter dedicated to the core power supply at 1.02V (up to 6 A) @ 2.4 MHz, with fine-tuning configurability from 0.99 V to 1.05 V
    • Overcurrent detection and limitation for all bucks
    • Integrated soft-start on buck stages
    • Boost controller 6 - 9 V with a max current capability of 3.5 A @ 400 kHz, for sustaining permanently low battery conditions and deep cranking pulses with boost modes
    • One 5 V voltage regulator (120 mA) for CAN-FD supply
    • One configurable (5 V or 3.3 V) low drop voltage tracker of buck regulator (10 mA)
    • One high-side driver for contact monitoring (RON = 55 Ω) with open-load and overcurrent diagnosis
    • Dedicated interrupt pin for failure communication
    • Device can operate in low-power mode
    • Very low quiescent current in deep sleep state
    • MCU reset generator
    • Configurable window watchdog with an extended long open window up to 9 s, with maskable function and enable/disable function through NVM bits
    • 1 CAN-FD transceiver (ISO 11898-2/2016 compliant), which can be deactivated via SPI, with local failure and bus failure diagnosis
    • Device contains temperature warning and protection
    • Thermal clusters
    • A/D conversion of supply voltages and internal temperature sensors
    • STMicroelectronics standard serial peripheral interface (32-bit / ST_SPI) including 4-bit CRC
    • One fail-safe output
    • One input pin supporting static and dynamic error signal reporting
    • Programmable periodic system wake-up feature
    • Programmable periodic system wake-up feature extended up to 180 days (Very Long Duration Timer)
    • Documentation available for customers that need support when dealing with ASIL requirements as per ISO26262
