BATTERY PROTECTION IC FOR SINGLE-CELL PACK S-8201 Series
The S-8201 Series are lithium-ion/lithium polymer
rechargeable battery protection ICs incorporating high-
accuracy voltage detection circuit and delay circuit.
The S-8201 Series 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),
• Overcharge release voltage
Accuracy ±25 mV (+25 °C), ±30 mV (−5 °C to +55 °C)
3.8 V to 4.4 V*1,
Accuracy ±50mV
• Overdischarge detection voltage 2.0 V to 3.0 V (10 mV step), Accuracy ±50 mV
• Overdischarge release voltage 2.0 V to 3.4 V*2,
Accuracy ±100 mV
• Overcurrent 1 detection voltage 0.05 V to 0.3 V (10 mV step) Accuracy ±15 mV
• Overcurrent 2 detection voltage 0.5 V (fixed)
Accuracy ±100 mV
(2) High voltage device is used for charger connection pins.
(VM pin and CO pin: Absolute maximum rating=28 V)
(3) Delay times (Overcharge: tCU, Overdischarge: tDL, Overcurrent 1: tlOV1, Overcurrent 2: tlOV2) are generated
by an internal circuit. (No external capacitor is necessary.)
Accuracy ±20%
(4) The overcharge timer reset delay time (7 ms to 40 ms) is generated by an internal circuit only. (No
external capacitor is necessary.)
(5) Three-step overcurrent detection circuit is included. (Overcurrent 1, Overcurrent 2, Load short-circuiting)
(6) Either charge function or charge inhibition function for 0 V battery can be selected.
(7) Charger detection function and abnormal charge current detection function
• The overdischarge hysteresis is released by detecting negative voltage at the VM pin (−0.7 V typ.).
(Charger detection function)
• When the output voltage of the DO pin is high and the voltage at the VM pin is equal to or lower than
the charger detection voltage (−0.7 V typ.), the output voltage of the CO pin goes low. (Abnormal
charge current detection function)
(8) Low current consumption
• Operation
3.5 µA typ., 7.0 µA max.
• Power-down
0.1 µA max.
(9) Wide operating temperature range −40 °C to +85°C
(10) Small package
6-Pin SOT-23-6, 6-Pin SNB(B)
*1. The overcharge hysteresis voltage is 0.0 V or can be selected from the range 0.1 V to 0.4 V in 50 mV
step.
Overcharge hysterests voltage (VHC)=Overcharge detection voltage−Overcharge release voltage
*2. The overdischarge hysteresis voltage is 0.0 V or can be selected from the range 0.1 V to 0.7 V in
100 mV step.
Overdischarge hysteresis voltage (VHD)=Overdischarge release voltage−Overdischarge detection
voltage
Applications
• Lithium-ion rechargeable battery packs
• Lithium polymer rechargeable battery packs
