ADVANCE INFORMATION

When a valid input source is connected (VIN > VINDPM and VBAT +VSLEEP < VIN < VIN_OVP), the state of the CE pin, CHARGE_DISABLE bit, and the TS/MR pin determines whether a charge cycle is initiated. When the CE pin or the CHARGE_DISABLE bit is set to disable charging, VHOT < VTS/MR < VCOLD and a valid input source is connected, the battery FET is turned off, preventing any kind of charging of the battery. Note that supplement behavior is independent of the CE pin or CHARGE_DISABLE bit. The device will be able to charge a battery as long as VIN voltage is higher than the VIN_LOWV threshold or VINDPM if enabled. This threshold is present as the VIN can be considered "powergood" with a very low battery voltage or a 0-V battery.
For devices with a dedicated CE pin, if either the charge disable bit is set to disable charging or the CE pin is high, the device will shut off charging to the battery. Both have to be set to enabled for charging to occur.
The following figure illustrates a typical charge cycle.
