MOSFET Switching Circuit Protects Shape Memory Alloy Actuators
- Created on Friday, 01 July 2011
A small-footprint, full surface-mount-component printed circuit board employs MOSFET (metal-oxide-semi-conductor field-effect transistor) power switches to switch high currents from any input power supply from 3 to 30 V.
