Hello,
I have a question for internal ESD diode current of MSP430G2332.
I found some similar posts on E2E and read SLAA689 application note, but I don’t have confidence whether the below case is safe or not.
The below is the case what I want to confirm.
A sensor output is maximum 7V. This sensor output is connected to AD input of MSP430G2322 through 1MOhm(High)/820KOhm(low) resistor divider.
This sensor is always powered even if MSP is NOT powered. It means a certain voltage could be input to AD input of MSP although MSP is not powered.
But due to the resistor divider, the current is less than 7uA. It is less than internal diode current limit. Is this case safe?
Regards,
Oba
