STCC08

AC switch failure mode detector

Features

■ 3.3 V and 5 V power supply compatible

■ ACS, ACST, TRIAC compatible

■ Gate driver output: 28 mA max sink current

■ Adjustable gate drive current

■ Sense the AC switch voltage in both AC line

polarities

■ Diode mode failure detection for solid state AC

switches

■ Short circuit failure detection for AC switches,

relays, electromechanical switches

■ Open AC switch detection for AC switches,

relays, electromechanical switches

■ SO-8 SMD package

Benefits

■ Enable appliances to meet IEC 60335-1 and

IEC 60730-1 standards

■ Enable appliances to meet IEC 61000-4-4

standard

■ Eliminates high DC current in inductive load, by

detecting the diode mode failure

■ Improve system safety monitoring open switch

failure with critical loads such as door locks

■ Enable MCU to sense all AC switch failure

modes and protect the appliance

■ Less MCU pin allocated to AC failure detection

multiple STCC08 designed with resistor

dividers uses one I/O

■ Easy to drive with MCU directly connected or

through an opto coupler

■ Highly compact with integrated solution in SMD

version

Applications

■ Home appliances

■ ACS, ACST, TRIAC drive

■ AC switch failure modes detection

■ Zero voltage synchronization

Description

The STCC08 is an AC switch failure mode

detector and an AC power switch driver. It drives

the AC switch and informs the MCU of switch

failure. The MCU takes the appropriate actions to

put the system in a secure state.

Diode-mode, short circuit detection and open

switch in both AC line polarities are detected.

The STCC08 helps home appliances to meet the

IEC 60335-1 safety standard.

The STCC08 can be easily interfaced to an MCU

with its CMOS input AC switch driver and CMOS

compatible output for the failure mode detector.
