Hello,
In a LiPo charger circuit, the battery voltage is input to a TPS22919, and the output of this component is then controlled by a power switch circuit.
If the battery is charging, when TPS22919 is disabled, Vout is 0.480V
If I disconnect the USB cable, which is the input to the charger, Vout goes down to 0.002V.
QOD pin is floating.
What is causing this voltage?
Thanks
