Other Parts Discussed in Thread: BQ25798
The latest datasheet (revised on March 2024) reports a current consumption of 56 uA over the VIN_3V3 pin in sleep mode. Such a value is still too high for my application. Is it possible to keep the device completely off while not connected to the USB-C? I would like to keep the quiescent consumption as close as zero during no USB charging conditions.
As I understood, if no supply is provided on that pin, the controller works in "dead battery" mode. Is it in fact supported the idea of disabling the power on VIN_3V3 everytime that the USB-C connector is removed? In principle, I could achieve such a behavior by disconnecting the local 3.3V rail with a FET based switch (controlled by my main MCU).
How will be the I2C configuration of a paired BQ25798 charger handled in this mode of operation?
Many thanks for your support
