SLUSA75B July 2010 – January 2020 BQ24650
The BQ24650 requires a voltage source between 5 V and 28 V connected to VCC. and VCC can be supplied either from the battery or the adapter. If the VCC voltage is greater than the SRN voltage, BQ24650 exits the SLEEP mode. If the SRN voltage is greater than VCC, BQ24650 enters a low-quiescent current (< 15 μA) SLEEP mode to minimize current drain from the battery.
