Product description: the Pololu DRV8801 single channel driver motors 36V/1A

The module is based on Texas Instruments DRV8801 allow you to control one DC motor. The motor can be powered with any voltage from 8 V to 36 V with a continuous current consumption up to 1 A, short-term (within seconds) to 2.8 A. Before use, we highly recommend you familiarizing yourself with the documentation system DRV8801. For lower supply voltages we have also dual channel modules DRV8833 and DRV8835.

Connection driver engines Pololu

 

Podłączenie jednokanałowego sterownika silników Pololu

In a typical application, simply connect the two lines of control: selection of rotation direction DIR( in the documentation called PHASE) and the speed control PWM (to ENABLE documentation). Default on-Board PWM signal is matched to the mass, and so the driver is disabled. Unless you need to use to adjust the speed of rotation must be specified at the PWM output state is high (logical unit).

 

Conclusion-the BREAK (in the documentation is referred to as MODE1) determines how the engine will behave at the zero cycle of the PWM (logical zero). By default, BREAK is chosen to power), in this case, if the PWM output is specified as low engine slows down dramatically (the insights are closed). Otherwise (BREAK in the low state), the engine will move freely (coasting). The options available are shown in the table below.
