Third generation power MOSFETs from Vishay provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness. The TO-220AB package is universally preferred for all commercial-industrial applications at power dissipation levels to approximately 50 W. The low thermal resistance and low package cost of the TO-220AB contribute to its wide acceptance throughout the industry.
“This little circuit allows your microcontroller to cut the power off. To turn the circuit on press the button. To turn it off drive the “to microcontroller” signal high using whichever condition you like. For battery applications you might want …
