9.3.5 Sleep Mode

The device enters the low-power sleep mode if the voltage IN falls below the sleep-mode entry threshold and VIN is higher than the undervoltage lockout threshold. In sleep mode, the input is isolated from the connected battery. This feature prevents draining the battery during the absence of VIN. When VIN < V(BAT) + VSLP, the device turns the battery discharge FET on, sends a 128-µs pulse on the INT output, and the FAULT bits of the register are update over I2C. Once VIN > V(BAT) + VSLP, the device initiates a new charge cycle. The FAULT bits are not cleared until they are read over I2C and the sleep condition no longer exists. It is not recommended to do a battery connection or plug in when VUVLO< VIN < VBAT + VSLP as it may cause higher quiescent current to be drained form the battery.
