Battery Protection IC for 4-serial to 5-serial Cell Pack S-82B4A/5A Series

Temperature protection function: Available (S-82C4A/5A) | Unavailable (S-82B4A/5A) 

This IC is a protection IC for lithium-ion rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. It is suitable for protecting 4-serial or 5-serial cell lithium-ion rechargeable battery packs from overcharge, overdischarge, and overcurrent.

Features

High-accuracy voltage detection for each cell
Overcharge detection voltage n: 3.900 V to 4.500 V (25 mV step) Accuracy ±20 mV
Overcharge release voltage n: 3.500 V to 4.500 V*1 Accuracy ±50 mV
Overdischarge detection voltage n: 2.000 V to 3.200 V (100 mV step) Accuracy ±50 mV
Overdischarge release voltage n: 2.000 V to 3.400 V*2 Accuracy ±100 mV
Three-level discharge overcurrent detection
Discharge overcurrent 1 detection voltage: 10 mV to 200 mV (5 mV step) Accuracy ±5 mV
Discharge overcurrent 2 detection voltage: 20 mV to 300 mV (5 mV step) Accuracy ±10 mV
Load short-circuiting detection voltage: 50 mV to 400 mV (10 mV step) Accuracy ±20 mV
Charge overcurrent detection
Charge overcurrent detection voltage: −200 mV to −10 mV (5 mV step) Accuracy ±5 mV
Discharge overcurrent 1 detection delay time is settable by an external capacitor (The other delay time are internally fixed)
Power saving control by a control pin

*1. Overcharge release voltage = Overcharge detection voltage − Overcharge hysteresis voltage
(Overcharge hysteresis voltage n can be selected from a range of 0 V to 0.4 V in 50 mV steps.)

*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage n can be selected from a range of 0 V to 0.7 V in 100 mV steps.)

Remark n = 1, 2, 3, 4, 5

Applications

  • Lithium-ion rechargeable battery packs
