The S-8230A/B Series is a protection IC for 1-cell lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy voltage detection circuits and delay circuits.
The S-8230A/B Series is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, overcurrent, and controlling discharge by external signal.

Features

High-accuracy voltage detection circuit
Overcharge detection voltage: 3.5V to 4.5V(5mV step), Accuracy of ±20mV(Ta = +25°C) , ±25mV(-10°C to +25°C)
Overcharge release voltage: 3.1V to 4.5V *1, Accuracy of ±30 mV
Overdischarge detection voltage: 2.0V to 3.4V (10 mV step), Accuracy of ±35 mV
Overdischarge release voltage; 2.0V to 3.4V *2, Accuracy of ±50 mV
Discharge overcurrent detection voltage: 0.05V to 0.20V (10mV step), Accuracy of ±10mV
Load short-circuiting detection voltage: 0.5V (fixed), Accuracy of ±100mV
Charge overcurrent detection voltage: −0.20 V to −0.05 V (25 mV step), Accuracy ±15 mV, −0.16 V to −0.08 V (40 mV step)
Detection delay times are generated only by an internal circuit (External capacitors are unnecessary).
Accuracy ±20%
Discharge control function
CTL pin control logic is selectable: Active “H”, active “L”
CTL pin internal resistance connection is selectable: Pull-up, pull-down
CTL pin internal resistance value is selectable: 1.0 MΩ, 2.5 MΩ, 5.0 MΩ
Discharge inhibition status latch function is selectable: Available, unavailable

Load disconnection, charger connection
High-withstand voltage device is used for charger connection pins:
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: 2.8 μA typ., 5.5 μA max. (Ta = +25°C)
During power-down: 0.1 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 packs
  • Lithium-polymer rechargeable battery packs
