MC33926 Motor Driver Carrier
 

This breakout board for Freescale’s MC33926 full H-bridge
has an operating range of 5 – 28 V and can deliver almost 3 A continuously (5 A peak) to a DC motor.
The MC33926 works with 3 – 5 V logic levels, supports ultrasonic
(up to 20 kHz) PWM, and features current feedback, under-voltage
protection, over-current protection, and over-temperature protection.
 

The MC33926 motor driver carrier can supply up to almost 3 A continuous
current to a single brushed DC motor at 5 – 28 V, and 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.
The MC33926 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, and a current feedback circuit outputs
an analog voltage on the FB pin that is proportional to the output current.
Since this board is a carrier for the Freescale Semiconductor MC33926 H-bridge,
we recommend careful reading of the MC33926 datasheet (1MB pdf).
