Please contact each Web shop for details such as availability of online samples.

The S-8240A Series is a protection IC for lithium-ion / lithium polymer rechargeable batteries and includes high-accuracy voltage detection circuits and delay circuits.
The S-8240A Series is suitable for protecting 1-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent.

Features

High-accuracy voltage detection circuit
Overcharge detection voltage: 3.5 V to 4.6 V (5 mV step) Accuracy ±20 mV
Overcharge release voltage: 3.1 V to 4.6 V*1 Accuracy ±50 mV
Overdischarge detection voltage: 2.0 V to 3.4 V (10 mV step) Accuracy ±50 mV
Overdischarge release voltage: 2.0 V to 3.4 V*2 Accuracy ±100 mV
Discharge overcurrent detection voltage: 0.015 V to 0.200 V (5 mV step) Accuracy ±5 mV
Load short-circuiting detection voltage: 0.065 V to 0.500 V (25 mV step)*3 Accuracy ±40 mV
Charge overcurrent detection voltage: -0.200 V to -0.015 V (5 mV step) Accuracy ±5 mV
Detection delay times are generated only by an internal circuit
(external capacitors are unnecessary).

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: 1.5 μA typ., 3.0 μA max. (Ta = +25°C)
During power-down: 50 nA max. (Ta = +25°C)
During overdischarge: 500 nA 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 from a range of 0 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 from a range of 0 V to 0.7 V in 100 mV step.)
*3. Load short-circuiting detection voltage = Discharge overcurrent detection voltage + 0.025 × n
(n can be selected from any integer value greater or equal to 2)

Applications

  • Lithium-ion rechargeable battery pack
  • Lithium polymer rechargeable battery pack
