Forum Post: RE: TPS40200 Must keep output switching off using SS Pin until 30 VDC input is available

Hi Dave,

One idea I have is the circuit below. When VDD is too low, the transistor on the right conducts pulling SS to ground. Once VDD pass the threshold determined by the resistor divider, the transistor on the left conducts turning off the right transistor and floating the SS pin.

Any thoughts?

Best Regards,
Anthony
