STCC08
AC switch failure mode detector-
Active
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.
