Charging_modified.pdf3323.charger.pdfPlease review my schematic.
CPU will monitor the charging status using STAT pin with 3.3V pull-up resistor.
I2C(SDA,SCL) and INT will connected to CPU with 10kohm and 3.3V pull-up resistor.
OTG pin needs to be defined. But Buck mode will be only feature to be used.
BATT(SYS) is the output to be connected to the all inside device.
QON needs to be defined. Shipping Mode?
2nd Question on 11/02 to Omid are below.
I have update the schematic. Please review one more time.
1) I have added 10uF at the SYS pin
2) I will Keep QON to open condition(NC) and will use plug in adapter to turned on from shipping mode. Is this correct? Does Plug in adapter mean the voltage changing at pin VBUS? So when I unplug and plug the charger to toggling VBUS pin, is it turned on?
