Hello,

What is the current rating of PG and nFLT for TPS259814ARPWR and where can I find that information in the datasheet.

Thanks.

Hi Michael,

We do not have this characterized for the device but by design few milliamperes is not an issue. How much current are you expecting in your application. The current can be easily reduced by changing the pull up resistor.

Do you have any specific concern?

Best regards,
Arush

10mA to also light an LED. Otherwise I will add external FET to switch the LED

Hi Michael,

The FET can handle 10mA current. In fact we also have LED in our EVM which are controlled using PG/FLTb pins.

Yeah I saw the TPS25981EVM had a LED for both with one being controlled through a FET. Thanks for the info sounds like we should be good then.
