Part Number: TPS61252

Dear all

Below is my SCH, there is 4.2V/3uA voltage on the Vout pin,the TPS61252DSG device is shutdown by EN pin, I want to know the device will be damaged when Vout pin has 4.2V/3uA voltage ?

Hi Went,

During shutdown, the load is completely disconnected from the battery. Vout pin maximum voltage rating is 7V.
What do you mean 4.2V/3uA? Do you mean you measure the Vout pin voltage is 4.2V when EN pin is pulled down?

Dear Zack
No,the 4.2V/3uA is not from TPS61252DSG device, is from USB_VBUS_CON, I worry about device will be damaged .

Hi Went,

4.2V is safe considering the maximum voltage rating is 7V.
