ST-828

Available Now!!! ST-828 NiCd / NiMH / Li-Ion Battery Seq. Twin Charge Control IC General 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 MiMH/NiCd 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 NiCd / NiMH 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 char...
