The two channels function as low-side or high-side drivers, integrating essential components to minimize external requirements. It regulates average current flow in loads up to 1500 mA with 0.73 mA resolution, and features a programmable triangular dither waveform generator for precise control.

機能

  • Two independent low side / high side configurable channels
  • Integrated half-bridge power stages
  • RON(max) = 250 mOhms@ Tj = 150 °C
  • Integrated sense resistor with internal TCR compensation
  • Load current measurement range = 0 mA to 1500 mA (typical)
  • Current setpoint resolution = 0.73 mA
  • Current control accuracy (-40C to 125C)
  • +/- 5mA for load currents less than 500 mA
  • +/- 1% for load currents greater than 500 mA
  •  Current control accuracy (-40C to 150C)
  •  +/- 7.5mA for load currents less than 500 mA
  •  +/- 1.5% for load currents greater than 500 mA
  • Excellent immunity to large load supply voltage changes
  • Integrated dither generator with programmable amplitude & frequency
  • SPI interface for output control, diagnosis, and configuration
  • Independent thermal shutdown for each channel
  • Open load, switch bypass, and over-current protection and diagnosis for each channel
  • Programmable slew rate control for reduced EMI
  • Green Product (RoHS compliant)
  • AEC Qualified

利点

  • +/- 1% Current Accuracy for Entire Channel (-40C to 125C)
  • Very Fast Current Step Response (dependent on solenoid characteristics)
  • Near ZERO Over/Under-shoot on step Response
  • Excellent Battery Ripple Rejection
  • AutoZero feature (automatically eliminates offset error)
  • Ease of use
  • Integrated Power Devices
  • Minimizes number of components placement, simplifies PCB layout
  • Enables current limitation, slew rate control and thermal protection
  • Improved Short-to-Battery performance
  • Integrated Shunt
  • Enables calibration of current accuracy at IC test
  • Simplifies module calibration
  • Active Recirculation
  • Reduces power dissipation
  • Enables integration
  • Enables HS/LS Configuration
