S-82P1A Datasheet, Specifications, Parts list and Support

Charge-discharge control function: Available (S-82P1A) | Unavailable (S-82P1B)

The S-82P1A Series 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 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent.
By using an external overcurrent detection resistor, the S-82P1A Series realizes high-accuracy overcurrent protection with less effect from temperature change.
The S-82P1A Series also has an input pin for charge-discharge control signal, allowing for charge-discharge control with an external signal.

Features

High-accuracy voltage detection circuit: Overcharge detection voltage: 3.500 V to 4.800 V (5 mV step) Accuracy ±15 mV; Overcharge release voltage: 3.100 V to 4.800 V^*1 Accuracy ±50 mV; Overdischarge detection voltage: 2.000 V to 3.000 V (10 mV step) Accuracy ±50 mV; Overdischarge release voltage: 2.000 V to 3.400 V^*2 Accuracy ±75 mV; Discharge overcurrent detection voltage 1: 3mV to 100 mV (0.25 mV step) Accuracy ±0.75 mV; Discharge overcurrent detection voltage 2: 6 mV to 100 mV (0.5 mV step) Accuracy ±2 mV; Load short-circuiting detection voltage: 20 mV to 100 mV (1 mV step) Accuracy ±5 mV; Charge overcurrent detection voltage: −100 mV to −3 mV (0.25 mV step) Accuracy ±0.75 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
Charge-discharge control function: CTL pin control logic: Active "H", active "L"; CTL pin internal resistance connection: Pull-up, pull-down; CTL pin internal resistance value: 1 MΩ to 6 MΩ (1 MΩ step)
Discharge overcurrent control function: Release condition of discharge overcurrent status: Load disconnection; Release voltage of discharge overcurrent status: Discharge overcurrent release voltage (V_RIOV) = V_DD × 0.8 (typ.)
Discharge overcurrent status reset function by CTL pin: Available, unavailable
0 V battery charge: Enabled, inhibited
Power-down function: Available, unavailable
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: 2.0 μA typ., 4.0 μA max. (Ta = +25°C); During power-down: 50 nA max. (Ta = +25°C); During overdischarge: 0.5 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.)

Applications

Lithium-ion rechargeable battery pack
Lithium polymer rechargeable battery pack

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.
