    Key features
    Key features
    • AEC-Q100 qualified
    • 2 configurable (6.5 V, 5 V, 3.3 V) BUCK converters and typ peak switching current limit of 3.0 A at 2.4 MHz or 400 kHz
    • 1 configurable (3.3 V, 1.25 V, 1.2 V, 1.1 V, 0.98 V) BUCK converter and typ peak switching current limit up to 6.0 A at 2.4 MHz, with fine-tuning configurability around 0.98 V (0.95 V to 1.01 V)
    • Overcurrent detection and limitation for all BUCKs
    • Integrated soft start on BUCK stages
    • Boost controller 8-9.5 V and typ peak switching current limit of 4.2 A at 400 kHz, for sustaining low battery condition occurring for a transitory time and deep cranking pulse (external power components can be optionally populated)
    • One 5 V voltage regulator (120 mA, 2% acc.)
    • One configurable (5 V or 3.3 V) low drop voltage tracker of all regulators (10 mA, ±10 mV)
    • One high side driver for contact monitoring (RON = 55 Ω) with open-load and overcurrent diagnosis
    • Dedicated interrupt pin for failure communication
    • Device operates in low power mode
    • Very low quiescent current in DEEP-SLEEP state
    • MCU reset generator
    • Configurable window watchdog with extended long open window up to 9 s and enable/disable function through NVM bit
    • 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
    • 1 fail-safe output
    • 1 input pin supporting static and dynamic error signal reporting
    • Programmable periodic system wake-up feature
    • Documentation available for customers that need support when dealing with ASIL requirements as per ISO26262
    • VFQFN56+4L 8x8x0.9 with wettable flank, 0.8 mm package
