BQ40Z50-R2: BQ40Z50-R2 / Disable zero-volt charging

S.Satoshi

Part Number: BQ40Z50-R2

Hi,

I know that bq40z50-R2 can support zero volt charging, but now the customer would like to disable zero volt charging. It means that they would not like to allow charging for the battery that has battery voltage below 1.1V. So please let me know if you have any option to disable zero-volt charging function.

Hi Satoshi,

If the customer wants to start pre-charge at 1.1V, then set Precharge Start Voltage to 1100mV.

If the customer wishes to disable the pre-charge function completely,setting Precharge Start Voltage and Charging Voltage Low = 0 mV disables the precharge function.
