Product Summary

The IR3220S is a fully protected dual high side switch I.C that integrates an H–bridge motor controller with two very efficient high side MOSFETs in a single 20-pin package. The IR3220S combines with the two low side IRF7484Q MOSFETs as few as 10 external passive components to provide a complete, fully operational and fully protected H-bridge control actuator with forward,reverse, braking and non-braking modes without the need of a micro-controller.
