Overview

The DRV8214 evaluation module (EVM) allows for easy evaluation of the DRV8214 device. The EVM has been programmed and configured to work out of the box and begin spinning motors right away.

The DRV8214 is an integrated motor driver with N-channel H-bridge, charge pump, current sense output, current regulation and protection circuitry. The DRV8214 integrates a ripple counting technology that allows for sensorless motor position monitoring, stall detection, and speed and voltage regulation. The tripler charge pump allows the device to operate down to 1.65 V to accommodate 1.8-V supply rails and low battery conditions. The charge pump integrates all capacitors and allows for 100% duty cycle operation. The EVM is accompanied by a GUI for easy control of the motor driver.

Features
  • 1.65-V to 11-V operating motor supply range
  • High output current capability: 4-A peak, 2-A RMS
  • Ripple counting for position monitoring and motor speed regulation
  • Adjustable op amp gain for high-accuracy current sensing down to 10 mA
  • Onboard eZ-FET lite debugger for MCU programming via USB
  • Supports 1.8-V, 3.3-V and 5-V logic inputs
