Texas Instruments DRV8251A | Demoboard DRV8251AEVM
DRV8251A 4.1-A Brushed DC Motor Driver with Integrated Current Sense and Regulation
Overview
| Topology | Motor Drive |
| Input voltage | 4.5-48 V |
| Switching frequency | 100-200 kHz |
| Output 1 | 48 V / 3.7 A |
Description
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.
Features
- N-channel H-bridge brushed DC motor driver
