Q: TPS386000 power up by 471914
Team,
one question regarding the power up / sequence of the TPS386000. As the datasheet does no show restrictions here i just want to make sure we have not overlooked something. It will have voltages conected via high impedance resistive dividers to some of the sensing inputs before the of the TPS386000 VCC ramps up. The max ratings of th part will be ensured. We want to know if this is a valid operating condition to apply a voltage to a SENSE pin before applying the input voltage to VCC. If voltage is applied to SENSE before VCC will the TPS386000 latchup?

You are correct that you can apply a voltage to the TPS386000 SENSE pins before you apply power to VCC.
