BATTERY PROTECTION IC
FOR 1- CELL PACK
S-8241 Series
Seiko Instruments Inc.
1
The S-8241 Series is a series of lithium-ion/lithium polymer rechargeable
battery protection ICs incorporating high-accuracy voltage detection
circuits and delay circuits.
These ICs are suitable for protection of single-cell lithium ion/lithium
polymer battery packs from overcharge, overdischarge and overcurrent.
Features
(1) Internal high-accuracy voltage detection circuit
Overcharge detection voltage: 3.9 V to 4.4 V (5 mV-step)
Accuracy of ± 25 mV(+25
°C) and ± 30 mV(5°C to +55°C)
Overcharge release voltage
3.8 V to 4.4 V
*1
Accuracy of ±50 mV
*1. Overcharge release voltage = Overcharge detection voltage - Overcharge hysteresis
The overcharge hysteresis can be selected in the range 0.0, or 0.1 to 0.4 V in 50mV steps.
(However, selection "Overcharge release voltage<3.8 V" is enabled.)
Overdischarge detection voltage: 2.0 V to 3.0 V (100 mV-step) Accuracy of ±80 mV
Overdischarge release voltage:
2.0 V to 3.4 V
*2
Accuracy of ±100 mV
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis
The overdischarge hysteresis can be selected in the range 0.0 to 0.7 V in 100mV steps.
(However, selection "Overdischarge release voltage
>3.4 V" is enabled.)
Overcurrent 1 detection voltage:
0.05 V to 0.3 V (5 mV-step) Accuracy of ±20 mV
Overcurrent 2 detection voltage:
0. 5 V (fixed) Accuracy of ±100 mV
(2) A high voltage withstand device is used for charger connection pins
(VM and CO pins: Absolute maximum rating = 26 V)
(3) Delay times (overcharge: tCU; overdischarge: tDL; overcurrent 1: tlOV1; overcurrent 2: tlOV2) are generated
by an internal circuit. (External capacitors are unnecessary.) Accuracy of ±30 %
(4) Internal three-step overcurrent detection circuit (overcurrent 1, overcurrent 2, and load short-circuiting)
(5) Either the 0 V battery charging function or 0 V battery charge inhibiting function can be selected.
(6) Products with and without a power-down function can be selected.
(7) Charger detection function and abnormal charge current detection function
The overdischarge hysterisis is released by detecting a negative VM pin voltage (typ. -1.3 V). (Charger
detection function)
If the output voltage at DO pin is high and the VM pin voltage becomes equal to or lower than the
charger detection voltage (typ. -1.3 V), the output voltage at CO pin goes low. (Abnormal charge current
detection function)
(8) Low current consumption
Operation:
3.0
A typ. 5.0 A max.
Power-down mode: 0.1 A max.
(9) Wide operating temperature range:
40 to +85 °C
(10) Small package
SOT-23-5, 5-Pin SON(A)
Applications
Lithium-ion rechargeable battery packs
