Pololu High-Power Motor Driver 36v9
Supports 5-50V for versatile applications
Delivers 9A continuous current efficiently
Features compact 1.3×0.8 in. design
Offers simple two I/O line interface
Detects short-circuit conditions effectively
The Pololu High-Power Motor Driver 36v9 is a discrete MOSFET H-bridge motor driver designed for bidirectional control of a high-power DC brushed motor. This compact board, measuring 1.3 by 0.8 inches, supports a wide voltage range from 5 to 50 volts and can deliver a continuous current of 9 amperes without the need for a heat sink. The driver is engineered to handle large DC brushed motors efficiently, with its performance largely determined by the N-channel MOSFETs that constitute the H-bridge.
The motor driver offers a straightforward interface, requiring minimal input/output lines for operation, and supports both sign-magnitude and locked-antiphase modes. It includes integrated detection for various short-circuit conditions, providing protection against common causes of failure. However, it lacks reverse power protection and over-current or over-temperature safeguards. The board's design facilitates easy connection to motor and control systems, with motor power connections on one side and control connections on the other.
For optimal performance, the motor supply should be capable of delivering high current, and a large capacitor is recommended to be installed close to the driver. The board includes a regulated 5V pin for low-power applications and provides fault detection through FF1 and FF2 pins. The driver can handle PWM frequencies up to 40 kHz, though higher frequencies may increase switching losses.
Note: The board does not include reverse power protection or over-current/over-temperature protection.

If you are not satisfied for whatever reason with a Product you bought on the Site, it is possible to return it for refund within 30 days from the date you received it unless otherwise indicated in the Product listing. You must first advise the Vendor associated with your order in your account to obtain a return authorization (‘’RA’’) number before returning a Product. (‘’RA’’) numbers are valid for 30 days, within which time the returned Products should be received by the Vendor. No returns will be accepted without having previously obtained an (‘’RA’’) number. The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product. Shipping fees will only be refunded if the return is a result of a shipping error on our part. Cleaning fees of USD 100 may also be charged if a domestic robot is returned and has not been properly cleaned.
