Part Number: TPS40422
I am using TPS40422 for FPGA Powers, For controlling Power on/off sequencing of different power rails I use the Reset Flag of Sequencer IC to
to Disable/Enable Converter, But I am not sure to which pin i should connect this Reset Flag. I mean which pin is the Enable/ Disable Pin of Coverter.
Thanking You in Advance for Help

In reply to Muhammad Kamran51:
Yes, use CNTL1 and CNTL2 to turn on and off ch1 and ch2.
CNTL1 and CNTL2 is pulled up to BP6 by an internal 6uA current source. That's means the pins will be high if they are open externally.
You can use open drain pin of sequencer to control CNTL1 and CNTL2 pins.
Btw, these basic information are available pin functions table on on datasheet page 3 and 4.
