Dear Group Members,
I am using CY8C4014SXI-421 in Touch Applications. Due to some reasons VCCD & VSS Pins are getting shorted. What could be the problem. I have interfaced Optocoupler with Port Pin and I am controlling 24V Relay with the optocoupler. In the end I am controlling AC BULB AND AC FAN via Relay. So what is the reason of VCCD Pin and VSS Pin shorting.
PSoC 4 MCU
Without your schematic I'll have to guess, there is a solder short across the capacitor connected to Vccd. This capacitor is connected between Vccd and Vss.
Good luck with your project.
Can you provide a screen shot of schematic showing Vccd, Vss, Vdd connections. I do not use latest PSoC Creator so I won't be able to open project.
Can you measure the Vccd voltage on a working Button. It should be around 1.8V.
