S-82C2A Datasheet, Specifications, Parts list and Support

This IC is a protection IC for lithium-ion / lithium polymer rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. It is suitable for protecting 2-serial-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent.

Features

High-accuracy voltage detection circuit: Overcharge detection voltage n: 3.500 V to 4.800 V (5 mV step) Accuracy ±20 mV; Overcharge release voltage n: 3.100 V to 4.800 V^*1 Accuracy ±50 mV; Overdischarge detection voltage n: 2.000 V to 3.000 V (10 mV step) Accuracy ±50 mV; Overdischarge release voltage n: 2.000 V to 3.400 V^*2 Accuracy ±75 mV; Discharge overcurrent 1 detection voltage: 3 mV to 400 mV (1 mV step) Accuracy ±3 mV; Discharge overcurrent 2 detection voltage: 10 mV to 400 mV (1 mV step) Accuracy ±5 mV; Load short-circuiting detection voltage: 20 mV to 800 mV (5 mV step) Accuracy ±10 mV; Charge overcurrent detection voltage: −400 mV to −3 mV (1 mV step) Accuracy ±3 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
0 V battery charge: Enabled, inhibited
Power-down function: Available, unavailable
Release condition of discharge overcurrent status: Load disconnection, charger connection
Release voltage of discharge overcurrent status: Discharge overcurrent release voltage (V_RIOV), discharge overcurrent 1 detection voltage (V_DIOV1)
High-withstand voltage: VM pin and CO pin: Absolute maximum rating 28 V
Wide operation temperature range: Ta = −40°C to +85°C
Low current consumption: During operation: 3.0 μA typ., 6.0 μA max. (Ta = +25°C); During power-down: 50 nA max. (Ta = +25°C); During overdischarge: 2.0 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 V to 0.4 V in 50 mV step.)
*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 V to 0.7 V in 100 mV step.)
Remark n = 1, 2

Parts List

U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
These descriptions may be different from the actual product name and parameter.
Please confirm the product name and specifications with the data sheet again.
