Overview
The T2117-TAQ is a zero-voltage switching integrated circuit manufactured by Microchip Technology, housed in an 8-SOIC package. Designed for bipolar technology applications, it functions as a control interface for triacs to manage resistive loads connected to mains power supplies. The device ensures switching occurs at the zero-crossing point of the AC waveform, which minimizes electromagnetic interference and electrical noise generated during load activation or deactivation.
Feature Summary
- Zero-voltage switching capability for reduced electrical noise
- Integrated control interface for triac-based loads
- Bipolar technology construction
Applications
- Mains-powered resistive load control
- Triac gate driving circuits
- Electromagnetic interference reduction in AC switching
Procurement Notes
Verify the manufacturer designation carefully, as the T2117 series was originally developed by Micrel, which was subsequently acquired by Microchip Technology. Ensure the specific suffix TAQ corresponds to the required 8-SOIC package variant. Confirm that the application involves resistive loads compatible with triac control logic before procurement.
Selection Notes
Select this component specifically for applications requiring low-noise switching of resistive loads on AC mains. It is suitable where minimizing electromagnetic interference is critical. Ensure the design utilizes a triac for load switching, as this IC provides the necessary zero-crossing trigger signal rather than direct load driving.
Part Context
The T2117 series belongs to a family of zero-voltage switch controllers designed for AC power control applications. Originally associated with Micrel, these components are now part of the Microchip Technology portfolio following corporate acquisition. The device serves as a specialized interface between digital control logic and high-power AC switching elements like triacs.
