Dual MC33926 Motor Driver Carrier (POLOLU-1213)

This is a placeholder topic for “Dual MC33926 Motor Driver Carrier” comments.

This dual brushed DC motor driver, based on Freescale’s MC33926 full H-bridge, has a wide operating range of 5 – 28 V and can deliver almost 3 A continuously (5 A peak) to each of its two motor channels. 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.

Hey does anyone know if the current sensors on this driver are bidirectional. Thanks

Looking at the datasheet it appears to be no. You’d really need a driver IC designed to handle regenerative braking - this one is meant as a throttle servo driver for a vehicle drive by wire system (spring close, drive open).

Ps. I noticed the datasheet link is http not https. Chrome has done a silly and silently fails to open http file links - you need to copy the link address and open it manually. This affects all Chrome based browsers, including Microsoft edge.

Pololu does have an SSL certificate though, so Core just needs to update the link in their product description.

Here’s the direct link:

Hi Oliver,

I’ve made that fix! It probably went unnoticed as Core staff use HTTPS Everywhere to force that ‘s’ in there :smiley:

I’m going to try and wrap my head around your response and see if I have any recommendations :slight_smile:
