    • 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).
