Please contact each Web shop for details such as availability of online samples.

The S-8211D 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

High-accuracy voltage detection circuit
Overcharge detection voltage: 3.6 to 4.5 V (5 mV steps) Accuracy ±25 mV (+25°C), Accuracy ±30 mV (−5 to +55°C)
Overcharge release voltage: 3.5 to 4.4 V*1 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 V*2 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 ±200mV
Detection delay times are generated by an internal circuit (external capacitors are unnecessary). Accuracy ±20%
High-withstand voltage (VM pin and CO pin: Absolute maximum rating = 28 V)
0 V battery charge function “available” / “unavailable” are selectable.
Power-down function “available” / “unavailable” is selectable.
Wide operating temperature range: Ta = −40 to +85°C
Low current consumption
During operation: 3.0 µA typ., 5.5 µA max. (Ta = +25°C)
During power-down: 0.2 µA max. (Ta = +25°C)
Lead-free, Sn 100%, halogen-free

*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.)

Applications

  • Lithium-ion rechargeable battery packs
  • Lithium-polymer rechargeable battery packs
