  • Key Features

    • AEC-Q100 qualified
    • Supply voltage from 4.2V to 54 V for working in single (12 V systems), double (24 V systems) and 48 V battery applications
    • The device can withstand -7 V to 90 V at the FET high-side Driver pins
    • Low standby current consumption
    • 3.3 V internal regulator supplied by Vcc pin
    • Boost regulator for full Rdson down to 6 V and over voltage protection
    • 3 low-side + 3 high-side drivers
      • PWM operation up to 20 kHz
      • Gate driver current adjustable via SPI in 4 steps. Range set via external resistor. Maximum gate controlled current 600 mA
      • Source connection to each MOSFET
    • Input pin for each gate driver
    • 2-differential current sense amplifiers:
      • Output offset selectable via SPI (0.2*Vcc offset for ground shunt resistors connection, 0.5*Vcc offset for phase shunt resistors connection)
      • All the amplifier gain factors are programmable (10, 30, 50, 100)
    • 8 MHz, 16-bit SPI
      • Full diagnostic
      • Programmable parameters:
        • Cross conduction dead time with a fixed minimum value
        • 4 current steps driving the PowerMOS gates (25%, 50%, 75%, 100%)
        • Phase or ground selection of current sense amplifier
        • Gain values for the current sense amplifiers
        • Zero current output voltage (offset) for the current sense amplifiers
        • Over voltage threshold selection for single or double battery operation
        • Short circuit detection thresholds for the low-side and the high-side MOSFETs (drain to source voltage monitor).
    • Protection and diagnostic
      • FET driver:
        • FET driver supply Undervoltage (UV) diagnostic;
        • Gate to source output voltage limit;
        • Gate to source passive switch off.
      • Power supply pins VB and VCC:
        • Overvoltage (OV), Undervoltage (UV) diagnostic and protection
      • All logic pins withstand 35 V
      • Power MOSFET drain to source voltage drop measurement for overcurrent protection
      • Over-temperature diagnostic and shutdown
      • Fault status flag output
