Description

The integrated circuit, T2117, is designed as a zero-voltage switch in bipolar technology. It is used to control resistive loads at mains by a triac in zero-crossing mode. A ramp generator allows power control function by period group control, whereas full-wave logic guarantees that full mains cycles are used for load switching.

Features

• Direct Supply from the Mains

• Current Consumption ≤0.5 mA

• Very Few External Components

• Full-wave Drive – No DC Current Component in the Load Circuit

• Negative Output Current Pulse

Typically 100 mA – Short-circuit Protected

• Simple Power Control

• Ramp Generator

• Reference Voltage

Applications

• Full-wave Power Control

• Temperature Regulation

• Power Blinking Switch
