Does VCCD pin have any circuit protection?
The customer is concerned about the following short.
Pin58.VCCD - Pin57.GND
Pin59. OUTPUT H - Pin58.VCCD
Hello @JuIn_1625121 ,
The datasheet mentions 1.1v threshold brown out detection (BOD) is made available on VCCD. The BOD is enabled by default. This should ideally ensure protection in both scenarios ( VCCD shorted with GPIO (5.5V) or VCCD shorted with VSSD ). Any deviation from the threshold would cause the MCU to reset.
Hi @JuIn_1625121 ,
I have tried to summarize the scenarios below:
1. Would a short between either VCCD and GPIO (5.5V) or VCCD and VSSD cause the device to short circuit/burn out?
2. As mentioned in the datasheet, 1.1V threshold Brown out detection (BOD) is provided on VCCD and is enabled by default, would this prevent the device from short circuit in the scenarios mentioned above?
In any case it is forbidden to short the pins you have mentioned.
