System Examples (continued)
Fs = 750kHz, IADPT = 2.048A, ICHRG = 1.984A, ILIM = 2.54A, VCHRG = 4.200V, 12W adapter and 1S2P battery pack
Use 0
Ω for better current sensing accuracy, use 10Ω/7.5Ω resistor for reversely battery connection protection. See
application information about negative output voltage protection for hard shorts on battery to ground or battery
reversely connection.
The total Csys is the total lump sum of system capacitance. It is not required by charger IC. Use Din for reverse input
voltage protection. See application information about reverse input voltage protection.

10 Power Supply Recommendations
When adapter is attached, and ACOK goes HIGH, the system is connected to adapter through ACFET/RBFET.
An external resistor voltage divider attenuates the adapter voltage before it goes to ACDET. The adapter detect
threshold should typically be programmed to a value greater than the maximum battery voltage, but lower than
the IC maximum allowed input voltage and system maximum allowed voltage.
When adapter is removed, the system is connected to battery through BATFET. Typically the battery depletion
threshold should be greater than the minimum system voltage so that the battery capacity can be fully utilized for
maximum battery life.
