Product overview

Description

The L9374LF is a SPI (serial peripheral interface) controlled four channel low side driver with integrated recirculation diodes.

The output duty cycle (all channels) / current regulation level (Q3 & Q4 only) can be programmed individually. It is possible to program two consecutive output duty cycles or target currents per channel as well as an individual duration time for each channel actuation.

  • All features

    • Four protected low-side drivers with diagnostics
      • Two 140 mΩPWM controlled outputs(Q1 & Q2)
      • Two 250 mΩ current controlled outputs with 6 % accuracy (Q3 & Q4)
    • All outputs with 35 V Zener Clamp
    • Programmable output timer
    • Clock monitor
    • Integrated recirculation diodes
    • 16 bit serial peripheral interface, up to 5 MHz with diagnosis
    • Battery compatible supply voltage
    • Detailed load diagnosis
      • Over load protection
      • Open load (off-state)
      • Undercurrent
      • Undervoltage
      • Temperature warning and shutdown
      • Power or signal GND loss
      • Freewheeling diode loss
      • Silent valve driver test
