The S-8209B Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes a high-accuracy voltage detection circuit and a delay circuit. This IC has a transmission function and two types of cell-balance function so that users are also able to configure a protection circuit with series multi-cell.
Overcharge detection voltage 3.9 V to 4.4 V (5 mV step) Accuracy ±25 mV
Overcharge release voltage 3.8 V to 4.4 V*1 Accuracy ±50 mV
Cell-balance detection voltage 3.9 V to 4.4 V (5 mV step)*2 Accuracy ±25 mV
Cell-balance release voltage 3.8 V to 4.4 V*3 Accuracy ±50 mV
Overdischarge detection voltage 2.0 V to 3.0 V (10 mV step) Accuracy ±50 mV
Overdischarge detection voltage 2.0 V to 3.4 V*4 Accuracy ±100 mV
Settable delay time by external capacitor for output pin
Control charging, discharging, cell-balance by CTLC, CTLD pins
Two types of cell-balance function; charge/discharge
Wide range of operation temperature
−40°C to +85°C
Low current consumption
7.0 µA max.
Lead-free product
*1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage (Overcharge hysteresis voltage is selectable in 0 V, or in 0.1 V to 0.4 V in 50 mV step.) *2. Overcharge detection voltage > Cell-balance detection voltage (Overcharge detection voltage is always set higher than Cell-balance detection voltage) *3. Cell-balance release voltage = Cell-balance detection voltage − Cell-balance hysteresis voltage (Cell-balance hysteresis voltage is selectable in 0 V, or in 0.1 V to 0.4 V in 50 mV step.) *4. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage (Overdischarge hysteresis voltage is selectable in 0 V, in 0.1 V to 0.7 V in 100 mV step.)
