MP2606 – SINGLE CELL 1A LINEAR LI-ION BATTERY CHARGER W/O TRICKLE CHARGE
Description
Input Supply Pin. IN receives the AC adapter or USB supply voltage.
Open-Drain Charge Status Indicator. This pin is low during charging.
Open-Drain Input ACOK Indicator. This pin is low if the voltage at the IN pin is between 2.5V
and 6V.
Charger IC Enable. An input “Low” signal at this pin or if the pin is floating will enable the IC.
Change Status Hysteresis Program Pin. (See the formular on page 7)
Ground.
Soft-Start Timer. Connect this pin to an external capacitor to program the soft-start startup time
using the equation:
Charge Status Threshold Program. Connect this pin to an external resistor to program the
charge termination current or battery full charge current.
Constant Charge Current Program. Connect this pin to an external resistor to program the
charging current in CC Mode.
