Other Parts Discussed in Thread: TPS22990
Dear Support Team,
This question is related to: https://e2e.ti.com/support/power-management/f/196/t/354708?tisearch=e2e-sitesearch&keymatch=tps22910a
TPS22910A ON input is active low.
1) In order to prevent output voltage during device start-up, I apply 5V to ON pin and only after that 5V to VIN pin. Such sequence will not be harmful to the device? Do I have any unexpected input current at ON pin?
2) In another scenario, I will pull-up ON pin through 10kOhm to 5V and VIN also will be 0V. And in rare cases 5V will be applied to VIN and ON signal will be toggled. Is such application permissible?
3) Is it possible to connect in parallel several TPS22910A in order to increase the continuos switch current rating?
Thank you
Andrei
