Functional description
STCC08 functional description
The STCC08 is a power circuit designed to drive up to 10 mA I
AC switch failure modes through MCU diagnostic.
It embeds a logic switch driver, an AC switch diode mode detection, a short circuit detection
and an AC switch open detection.
STCC08 can be powered by a 3.3 V or 5 V power supply voltage.
Switch driver
This driver is a logic level buffer (CMOS compatible) interfacing directly with the AC switch
and the microcontroller.
The AC switch must be driven in negative polarity: AC switch COM = A
The drive Boolean rule is:
V
V
The AC switch can be driven in continuous, pulsed or angle phase modes.
In insulated applications, the input can be driven through an opto-coupler powered with a
non-insulated auxiliary power supply.
