Product Summary

The TDA1085C is a phase angle triac controller which has all the necessary functions for universal motor speed control in washing machines. It operates in closed loop configuration and provides tworamp possibilities. Motor speed is digitally sensed by a tachogenerator and then converted into an analog voltage.
The speed set is externally fixed and is applied to theinternal linear regulation input after having been submitted to programmable acceleration ramps. The overall result consists in a full motor speed range with two accelerationramps which allow efficient washing machine control(Distribute function).
Additionally, the TDA1085C protects the whole systemagainst AC line stop or variations, overcurrent in the motorand tachogenerator failure
