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.
