Hi! I am using TPS25740B for a 5V/3A charger application.
I have a problem with the GDNG pin as it turns on and off. Upon checking the datasheet, the GDNG will output a square wave when
1) it detects a short between the VBUS and GND, and
2) when the junction temperature Tj exceeds Tj1.
When I checked, my VBUS and GND are not shorted and the IC is not hot.
What may be the other cause for the continuous turning on and off of the GDNG?
