This MOSFET switch is designed to safely power the NM70R-6P shape memory alloy actuator across a wide range of speeds or input voltages. It allows either push-button control, or external Gate or CNTL signals (from 2.5-30V) to actuate the NM70R-6P memory metal actuator until the end-of-travel is reached.
It then cuts power momentarily, preventing overheating of the shape memory "muscle" wires.
