ZS6093RevisionZS6093 SHENZHEN ZASEMMICROELECTRONICS CO.,LTD. Page15A,Multi-Chemistry Battery ChargerICWithPhotovoltaicCell MPPTFunctionZS6093General Descriptions:The ZS6093(Note 1) is a PWM switch-mode batterycharger controller that can be powered by photovoltaiccell with maximum power point tracking function. TheZS6093 is specially designed for charging 1 ormulti-cell lithium ion batteries or LiFePO4 batterieswith constant current and constant voltage mode. Inconstant voltage mode, the regulation voltage is set bythe external resistor divider. The constant chargingcurrent is programmable with a single current senseresistor.Deeply discharged batteries are automatically tricklecharged at 15% of the programmed constant chargingcurrent until the cell voltage exceeds 66.7% of theregulation voltage. In constant voltage mode, thecharging current decreases gradually, the charge cyclewill be terminated when the charging current drops to9.5% of the full-scale current, and a new charge cycleautomatically restarts if the battery voltage falls below95.8% of the regulation voltage in constant voltagemode.ZS6093 will automatically enter sleep mode wheninput voltage is lower than battery voltage. Otherfeatures include undervoltage lockout, batterytemperature monitoring and status indication, etc.ZS6093 is available in a space-saving 16-pin TSSOPpackage.Applications: The Charger Powered by Photovotaic cell Electric Tools Battery-Backup Systems Standalone Battery ChargersNote 1: Patent PendingFeatures: Photovoltaic Cell Maximum Power PointTracking Wide Input Voltage: 7.5V to 28V Complete Charger Controller for 1 ormulti-cell Lithium-ion Battery or LiFePO4Battery Charge Current Up to 5A High PWM Switching Frequency: 300KHz Constant Charging Voltage Set By theExternal Resistor Divider Charging Current is programmedwith a sense resistor Automatic Conditioning of DeeplyDischarged Batteries Battery Temperature Monitoring 2 Status Indications Soft Start Battery Overvoltage Protection Operating Ambient Temperature－40℃ to ＋85℃ Available in 16 Pin TSSOP Package Pb-free , RoHS Compliant,and Halogen FreePinAssignment:ZS6093Revision ZS6093 SHENZHEN ZASEMMICROELECTRONICS CO.,LTD.
