General Description
PIN # 1, 15, 16 2 3 4 5 6 7 8 PIN NAME VIN GRN RED TIME GND DT EN V2P9 DESCRIPTION VIN is the input power source.
It is recommended to have a 1Ω resistor in series with the input decoupling capacitor to prevent an over-shoot voltage when the input cable is plugged in.
Open-drain LED drive pin.
Key Features
- include improved accuracy, pre-charge circuit verification, and enhanced LED indicator function. Working with a current-limited AC/DC converter, the dualmode charger charges a Li-ion battery with the same current profile as a traditional linear charger. The constant charge current is determined by the current limit of the AC/DC converter. The constant output voltage is fixed at 4.2V. When the battery voltage is below 2.8V, the charger preconditions the battery with a low trickle-charge current.
