Sales Briefcase
  • The L9781 is a multi valve pre-driver capable of driving 11 external N-channel logic level MOSFETs, controlling up to 5 inductive loads through peak and hold current control and one DC/DC step-up converter, providing full protection against accidental faults on the external hardware. The load peak and hold current control (together with the diagnosis) is done by the internal configurable Finite State Machines (FSMs) needing only the start of actuation commands from the main microcontroller.

    主要特性

    • AEC-Q100 qualified
    • 1 x DC/DC converter controller for VTank voltage generation (up to 80 V):
      • 1 x low-side push-pull type N-channel MOSFET pre-driver
      • 1 x current sensing block for current limitation
      • 1 x voltage comparator with hysteresis for VTank voltage sensing
    • 2 x driving channel controllers each made up of:
      • 1 x high-side push-pull type VTank N-channel MOSFET pre-driver
      • 1 x high-side push-pull type VBat N-channel MOSFET pre-driver
      • 2 x low-side push-pull type N-channel MOSFET pre-driver
      • 1 x differential amplifier with programmable gain for current sensing & peak current detection
      • 1 x digital-to-analog converter for peak current threshold setting
      • 1 x HW protection and diagnosis block for full load protection from accidental external short circuits
    • 1 x additional peak and hold controller:
      • 1 x high-side push-pull type VBat N-channel MOSFET pre-driver
      • 1 x low-side push-pull type N-channel MOSFET pre-driver
      • 1 x differential amplifier with programmable gain for current sensing and peak current detection
      • 1 x digital-to-analog converter for peak current threshold setting
      • 1 x HW protection and diagnosis block for full load protection from accidental external short circuits
    • 1 x 32 bit SPI interface (up to 8 MHz)
      • IC general control
      • Programmable parameters setting
      • Diagnosis and hardware protection management
