ST-828 Datasheet | Chips Garden

Description LM339 associate with advance software program to achieve the goal of constant-current and constant-voltagecontrol. Especially suitable for the up-to-date Li-Ion battery charge control and Mi MH/Ni Cd battery are also available. Main Function constant-current (C.C.) charge technique and provide -∆V/∆t, Timer, V-Max, terminatecondition detection Apply trickle charge current after battery was full-charged. For Li-Ion battery apply constant-voltage (C.V.) charge technique to ensure safety and prevent battery from damage. Provide battery chemistry type input selection, allow system to identify battery type via proper interface circuit. Support LED/LCD display. Provide battery power indicator (LCD mode) to illustrate the battery power in percentage. Support battery discharge function. 16 Pin SOP Package For Ni Cd / Ni MH battery apply ST-828 has the most simplest and economic way by using the ST-828 for the phone-set which built-in charge-control function itself, provide a simplest solution to detect the charge status of phone-set. Basically, the phone-set will has higher priority to charge than the battery if both in their own slot. System will monitor the charging status of phone-set and detect the "charge-terminate" situation of phone-set and then transfer the charge process to the battery. ST-828 support LED/LCD indicators could illustrate the condition during charging (Red-LED for Rapid-Charge, Green-LED for Full-Charged in LED display mode, and 25%, 50%, 75%, 100% for charging power indicator in LCD display mode). ST-828 is the best cost performance IC to achieve the goal of higher quality and lower the cost of twin charger solution.
