Part Number: TPS22997

Tool/software:

Hi team,

Is there a power sequence required for the device to work properly? For example: VIN => VBIAS => EN or VBIAS => VIN => EN.

Hello Sam,

VBIAS can be a permanent source or tied to VIN.

So, VIN=VBIAS then EN pin to turn ON the switch.

Thanks

Hi Amrit,

Can I say that the recommended order is
1) VBIAS => VIN => EN
2) VBIAS = VIN => EN

Thanks!
