Texas Instruments DRV8251 | Demoboard DRV8251EVM
DRV8251 4.1-A Brushed DC Motor Driver with Integrated Current Regulation
Overview
| Topology | Motor Drive |
| Input voltage | 4.5-48 V |
Description
The DRV8251 evaluation module (EVM) allows for easy evaluation of the DRV8251 device. The EVM has been programmed and configured to work out of the box and begin spinning motors right away.The DRV8251 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 DRV8251 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 DRV8251 can be controlled by an external controller.
Features
- 4.5-V to 48-V operating voltage
- Up to 3.7-A motor peak current
- Precise control signal duty cycle adjustment via potentiometers
- Support external MCU control of the DRV8251A
Typical applications
- Washer and dryer, Coffee machine, ATMs (Automated Teller Machines), Ventilators, Surgical equipment, Fitness machine
- Printers, POS printer
- Vacuum robot, Electronic hospital bed and bed control
