Other Parts Discussed in Thread: BQ28Z610
The customer are using BQ28Z610 and take measurement. If the battery is set as 2V (Vbat+ is 2V) and the adapter plug in, the CHG pin voltage is 3.9V (1.9V higher than the Vbat+).
1.So the customer want to know whether it is this normal?
2. Whether the CHG gate voltage is fixed? Because this will affect the chose of CHG FET.
3. Is there any description of the hardware 0-V charging circuit?
