Motor driver 1-ch 4.5-48V 1.9A DRV8256E

Texas Instruments' DRV8256E is a tiny H-bridge motor driver IC that can be used for bidirectional control of a single brushed DC motor at 4.5 V to 48 V. It can supply up to about 1.9 A continuously and can tolerate peak currents up to 6.4 A for a few seconds, making it a good choice for small motors that run on a wide range of voltages. Since this board is a carrier for the DRV8256E, we recommend careful reading of the DRV8256 datasheet. The board ships populated with all of its SMD components, including the DRV8256E.

This DRV8256E uses a phase/enable interface that allows bidirectional control with only one PWM signal, but it is limited to drive/coast operation. The very similar DRV8256P has an IN/IN interface instead, requiring two PWM signals for full bidirectional control, but it offers drive/brake operation (which usually provides a more linear relationship between PWM duty cycle and motor speed).

* Drives a single brushed DC motor
* Motor supply voltage: 4.5 V to 48 V
* Supports 1.8 V to 5 V logic voltage (5.5 V max)
* Output current: 1.9 A continuous (6.4 A peak)
* Simple interface requires only two I/O lines (one for direction and another for speed)
* Under-voltage lockout and protection against over-current and over-temperature
* Carrier board adds reverse-voltage protection up to 40 V
* Compact size (0.6"×0.6")
