This reference design drives 8 seven-segment digits with brightness control, using a low-cost MSP430 and two DRV8860 octal low-side drivers. The display module gain benefits from DRV8860 on wide supply range, high current capability, PWM brightness control, serial daisy chain connection and expandable outputs for hundreds of LEDs. A complete solution and six demo display patterns are provide with the on-board MCU program along with the integrated protection from short-circuit, under voltage, and over-temperature.

  • Serial interface minimizes the number of signals
  • Drives 8 characters with only two DRV8860
  • Small PCB footprint
  • Extendable output current capability for super bright LEDs
  • Internal 8-level PWM duty for brightness control via serial interface
  • Six demo display patterns provided with the on-board MCU
