Pololu - 2737

The Pololu Pushbutton Power Switches are sophisticated power control alternatives to bulky mechanical switches. The main function is pushbutton-based latching power control, where one push turns on power and another push turns it off.

This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 1.3″ × 0.8″ board supports a wide 6.5 V to 30 V voltage range and is efficient enough to deliver a continuous 17 A without a heat sink.

This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 1.3×0.8″ board supports a wide 6.5V to 40V voltage range and is efficient enough to deliver a continuous 13A without a heat sink. Driver includes reverse-voltage protection along with basic current sensing and current limiting functionality. Pololu 2992
