Sales Briefcase
  • The L9305 is a configurable, monolithic solenoid driver IC designed for the control of linear solenoids for automatic transmission, electronic stability control, and active suspension applications. The four channels can be configured as either low side or high side drivers in any combination. The device includes the power transistor, recirculation transistor and current sensing for both the power and recirculation transistor. This architecture guarantees redundancy of the current measurement for each channel.

    The regulated current is programmable in the range of 0-1.5 A (normal range), with a resolution of 0.25 mA, or 0-2 A (extended range), with a resolution of 0.33 mA. The user can superimpose configurable dither modulation over the set point current.
    A 32-bit CRC protected SPI interface is used for configuration and control of all channels and provides status feedback of all diagnostic functions. An active low reset input, RESN, is used to disable all channels and resets internal registers to their default values. A safe enable path is provided through the EN_DR pin and the integrated Fail Safe Pre-driver. An isolated redundant safety switch-off path ensures that critical internal faults disable the fail safe pre-driver. An active high enable pin, EN_DR, is used to enable or disable the operation of all channels. When the EN_DR pin is low, all channels are disabled. A fault output pin is provided and can be used to generate an external interrupt to the microcontroller whenever a fault is detected. The user can map specific faults to the FAULTn pin based on their specific system requirements.
