DRV821x and DRV823x Evaluation Module
Description
The DRV821x or DRV823x evaluation module (EVM)
allows for easy evaluation of the DRV8213, DRV8214,
DRV8215, DRV8234, and DRV8235 devices. The
EVM has been programmed and configured to work
out of the box and begin spinning motors right
away. The EVMs showcase an integrated motor
driver with N-channel H-bridge, charge pump, current
sense output, current regulation, and protection
circuitry. The DRV8214 and DRV8234 integrate a
ripple counting technology that allows for sensorless
motor position monitoring, stall detection, and speed/
voltage regulation. The DRV8215 and DRV8235
integrate stall detection and speed/voltage regulation.
DRV8213 integrates stall detection. The charge pump
integrates all capacitors and allows for 100% duty
cycle operation. The EVM is accompanied by a GUI
application for easy control of the motor driver.
