Hi team,
Here is the schematic.
When adapter is plugged in (battery is attached,battery is 3.9V now, the typ value should be 4.2 when it is full), it is found no charging is ongoing.
Below is the waveform in the condition--adapter is plugged in, and no battery, the output is about 3.55V, which should be correct in 15min mode.
When the battery is plugged in, the waveforms are below, the switching could be seen at s 5ms span.
And also, customer finds that, if the battery is attached before adapter plugged in, the Vref=0V. If the battery is attached after the adapter is plugged, the Vref=5V.
Below is the setting of register.(default value) The I2C communication is verified OK by customer.
reg:0x0, val:0xc0
reg:0x1, val:0x30
reg:0x2, val:0xa
reg:0x3, val:0x51
reg:0x4, val:0x9
reg:0x5, val:0x24
reg:0x6, val:0x40
Any suggestion?
Thanks.
