The DRV8426E evaluation module (EVM) allows easy evaluation of the DRV8426E device.

The DRV8426E devices are integrated motor-driver solutions for bipolar stepper motors or brushed DC motors. The device integrates two N-channel power MOSFET H-bridges, integrated current sense and regulation circuitry. The DRV8426E devices can be powered with a supply voltage from 4.5 to 33 V. A simple PHASE/EN control interface allows for an external controller to manage the outputs. The decay mode can be selected as a slow, mixed decay, smart tune Ripple Control, or smart tune Dynamic Decay current regulation scheme.

For more information on this evaluation module please refer to the DRV84xxEVM User's Guide.

  • 4.5-V to 33-V operating voltage range
  • Up to 2.5-A Peak current
  • A simple PHASE/EN input interface
  • Integrated current sense
  • Smart tune technology
