ZHCSJD3B July 2018 – February 2019 BQ25150
The following diagram summarizes the charging process of the BQ25150 charger.
When a valid input source is connected (VIN > VUVLO and VBAT+VSLP < VIN < VOVP), the state of the CE pin determines whether a charge cycle is initiated. When the CE input is high and a valid input source is connected, the battery charge FET is turned off, preventing any kind of charging of the battery. A charge cycle is initiated when the CHARGE_DISABLE bit is written to 0 and CE pin in low. The following table shows the CE pin and bit priority to enable/disable charging.
|/CE PIN||CHARGE _DISABLE BIT||CHARGING|
The following figure shows a typical charge cycle.
