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.
The S-82C2B Series has an input pin for charge-discharge control signal (CTL pin), allowing for charge-discharge control with an external signal. The S-82C2C Series has an input pin for power-saving signal (PS pin), allowing for reduction of current consumption by using an external signal to start the power-saving function.

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 ±3.0 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 ±3.0 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).

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.)

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.
