Tool/software:
Hi!
The BQ25798 has an automatic way to switch from charger to backup mode, when EN_BACKUP = 1 and VBUS falls below the threshold.
Is there any way to switch from backup mode to normal charger operation (when an adapter is connected to the power input VIN1) without host intervention? E.g. when the BQ25798 is operating in backup mode and power is restored.
2nd Question: how should we treat D+/D- inputs when the USB detection is not used? With a pulldown resistor or connection to GND?
Regards!
