- 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.

- Data Sheet (MC33926 H-Bridge)
- Overview
- Motor driver: MC33926
- Motor channels: 1
- Minimum operating voltage: 5 V (Operation from 5 - 8 V reduces maximum current output)
- Maximum operating voltage: 28 V (The device is protected for transients up to 40 V)
- Continuous output current per channel: 2.5 A (Can be improved by addition of heat sink or forced air flow)
- Peak output current per channel: 5 A
- Current sense: 0.525 V/A
- Maximum PWM frequency: 20 kHz (SLEW pin should be HIGH for frequencies above 10 kHz)
- Minimum logic voltage: 2.5 V (Input HIGH threshold can be as high as 2.0 V)
- Maximum logic voltage: 5.5 V
- Reverse voltage protection?: Y (On motor voltage only; logic voltage does not have reverse protection)
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.
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.
Simple à utiliser. Riche ensemble de fonctionnalités telles que l'indicateur de panne et le retour d'informations actuel. De nombreuses broches sont exposées et nécessitent un actionnement haut / bas pour que le moteur fonctionne. C'est une bonne chose que le module vienne avec des "cavaliers" montés / descendants situés à côté de leurs broches respectives. Utilisé 12V à environ 1A et la puce est à peine chaude.
Le module est simple à utiliser et facile à mettre en œuvre. Je l’utilise en configuration 24V et tout est bon.

Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
- A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
- The RA number is valid for 30 days. The returned item must be received within that period.
- The RA number must be included with the return.
- Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
- Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
- Refunds are processed within 7 days after receipt and inspection of the returned item.
- A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
- A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
- Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
- Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
- Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
- Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
- Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
