  • Features current feedback, and under-voltage protection
  • Also features over-current protection and over-temperature protection

The Pololu DC Motor Driver 3A, 5V-28V- MC33926 is a breakout board for Freescale's MC33926 full H-bridge. It has an operating range of 5 - 28 V and can deliver almost 3 A continuously (5 A peak) to a single brushed DC motor. This DC motor driver works with 3 - 5 V logic levels. It supports ultrasonic (up to 20 kHz) pulse width modulation (PWM) of the motor output voltage which eliminates the audible switching sounds caused by PWM speed control. It can tolerate peak currents up to 5 A for a few seconds, making this a great general-purpose motor driver for medium-sized DC motors. Moreover, it features current feedback, under-voltage protection, over-current protection, and over-temperature protection. Since this board is a carrier for the Freescale Semiconductor MC33926 H-bridge, careful reading of the MC33926 datasheet is recommended.

Quiet and simple to use

Straight forward to use. Rich set of features such as fault flag and current feedback. Many pins are exposed and require pull up/down for the motor to run. Good thing the module comes with pull up/down "jumpers" conveniently located next to their respective pins. Used 12V at about 1A and the chip is barely warm.

Expected a easy to use implement module a got exactly that

The the module is straight forward to use and is easy to implement I am using it in a 24V configuration and it is all good.
