Application information

Figure 5.

Application example with an MCU direct drive + ACS

advised. SW is an electromechanical switch that is part of the application design, for

example, the water sensor in a washing machine.

3.1

Recommendations

The STCC08 is designed for 5 and 10 mA ACSs, ACSTs and TRIACs.

STCC08 basic application

The microcontroller reads the AC switch state from the AVF output of the STCC08. The

microcontroller can power-off the application driving a front-end relay.
