Product Summary

The TDA2086 is a silicon integrated circuit designed for use in closed or open loop phase control circuits of AC with resistive or inductive loads. In closed loop systems analog voltage or tacho frequency feedback may be used. The TDA2086 was primarily designed for motorspeed control in power drills food mixers washing machines etc. In the event of an open circuit tacho generator connection the TDA2086 will demand full speed/power.
