This compact breakout board for TI’s DRV8256P motor driver offers a wide operating voltage range of 4.5 V to 48 V and can deliver a continuous 1.9 A (6.4 A peak for <1 second) to a single brushed DC motor. It features a two-pin IN/IN interface for direct control of the motor outputs and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature.
Texas Instruments’ DRV8256P 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 DRV8256P, we recommend careful reading of the DRV8256 datasheet.
The board ships populated with all of its SMD components, including the DRV8256P.
This DRV8256P has an IN/IN interface that requires 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). The very similar DRV8256E uses a phase/enable interface instead, allowing bidirectional control with only one PWM signal, but it is limited to drive/coast operation. We sell another version of this carrier board with the DRV8256E; the two versions can be distinguished by the markings on the driver chip.
