特性 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
