**The S-8211C Series are protection ICs for single-cell lithium-ion /
lithium polymer rechargeable batteries and include high-accuracy voltage detectors and delay circuits.**
These ICs are suitable for protecting single-cell rechargeable lithium-ion / lithium polymer battery packs from overcharge, overdischarge, and overcurrent.
Features
(1) High-accuracy voltage detection circuit
• Overcharge detection voltage 3.9 to 4.4 V (5 mV steps) Accuracy ±25 mV (+25 °C) Accuracy ±30 mV (−5 to +55 °C)
• Overcharge release voltage 3.8 to 4.4 V1 Accuracy ±50 mV
• Overdischarge detection voltage 2.0 to 3.0 V (10 mV steps) Accuracy ±50 mV
• Overdischarge release voltage 2.0 to 3.4 V2 Accuracy ±100 mV
• Discharge overcurrent detection voltage 0.05 to 0.30 V (10 mV steps) Accuracy ±15 mV
• Load short-circuiting detection voltage 0.5 V (fixed) Accuracy ±200 mV
• Charge overcurrent detection voltage −0.1 V (fixed) Accuracy ±30 mV
(2) Detection delay times are generated by an internal circuit (external capacitors are unnecessary). Accuracy ±20%
(3) High-withstanding-voltage device is used for charger connection pins (VM pin and CO pin : Absolute maximum rating = 28 V)
(4) 0 V battery charge function available / unavailable are selectable.
(5) Wide operating temperature range −40 to +85 °C
(6) Low current consumption
• Operation mode 3.0 µA typ., 5.5 µA max. (+25 °C)
• Power-down mode 0.2 µA max. (+25 °C)
(7) Small package SOT-23-5, SNT-6A
(8) Lead-free product***1. Overcharge release voltage = Overcharge detection voltage −
Overcharge hysteresis voltage(Overcharge hysteresis voltage can be selected as 0 V or from a range of 0.1 to 0.4 V in 50 mV steps.)**
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage(Overdischarge hysteresis voltage can be selected as 0 V or from a range of 0.1 to 0.7 V in 100 mV steps.)
