This product has been discontinued.

This product has been replaced by an improved second-generation version, which can be used as a near drop-in replacement despite its much smaller size.

This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The little 1.8×0.8-inch board supports a wide 5.5 to 30 V voltage range and is efficient enough to deliver a continuous 25 A without a heat sink.
