Kazuhiko Hirano

Part Number: TPS22990

Hello,

With which power supply does the QOD circuit work, Vin or Vbias?
How much minimum power supply voltage is required for the QOD circuit to work?

Best regards,

Hi Hirano-san,

The VBIAS voltage powers the device and sets the internal references. It also powers the QOD circuit.

The minimum voltage for this pin is 2.5V.

Thanks,

Shreyas
