Substantially reduce heat generation of the protection circuit board and cope with the need for quick charging S-82Y1B Series

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 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent.
Use of an external overcurrent detection resistor enables this IC to provide high-accuracy overcurrent protection with less impact from temperature changes.

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 1 detection voltage: 3 mV to 50 mV (0.25 mV step) Accuracy ±0.5 mV
Discharge overcurrent 2 detection voltage: 6 mV to 100 mV (0.5 mV step) Accuracy ±1.5 mV
Load short-circuiting detection voltage: 15 mV to 100 mV (1 mV step) Accuracy ±3.0 mV
Charge overcurrent detection voltage: −50 mV to −3 mV (0.25 mV step) Accuracy ±0.5 mV
Detection delay times are generated only by an internal circuit (external capacitors are unnecessary).
Discharge overcurrent control function
Release condition of discharge overcurrent status: Load disconnection
Release voltage of discharge overcurrent status: Discharge overcurrent release voltage (VRIOV) = VDD × 0.8 (typ.)

*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
