Texas Instruments DRV8251A | Demoboard DRV8251AEVM

Beschreibung

The DRV8251A evaluation module (EVM) allows for easy evaluation of the DRV8251A device. The EVM has been programmed and configured to work out of the box and begin spinning motors right away.The DRV8251A is a 4.5V to 48-V rated single H-bridge driver capable of driving up to 3.7 A. The EVM allows for easy control of the DRV8251A wihout the need of a GUI. The EVM comes equiped with two potentiometers which allow for adjustment of the control signal duty cycle. If desired, the on-board MCU can be disconnected so the DRV8251A can be controlled by an external controller.
