3. TECHNICAL BRIEF

Constant Current Charging

The PM7540 IC supports constant current charging of the main battery by controlling the charger pass

transistor and the battery transistor. The constant current charging continues until the battery reaches

its target voltage, 4.2V.

Constant Voltage Charging

Constant voltage charging begins when the battery voltage reaches a target voltage, 4.2V.

The end of constant voltage charging is commonly detected 10% of the full charging current.

• Charging Method : CC & CV (Constant Current & Constant Voltage)
• Maximum Charging Voltage : 4.2V
• Maximum Charging Current : 660mA
• Nominal Battery Capacity : 900mAh
• Charging time : Max. 3h 30m
• Full charge indication current (icon stop current) : 50mA
• Cut-off voltage : 3.30V
