• Overcharge detection voltage:
• Overcharge release voltage
• Overdischarge detection voltage:
• Overdischarge release voltage:
• Overcurrent 1 detection voltage:
• Overcurrent 2 detection voltage:
• The overdischarge hysterisis is released by detecting a negative VM pin voltage (typ. -1.3 V). (Charger
• If the output voltage at DO pin is high and the VM pin voltage becomes equal to or lower than the charger
• Operation:
• Power-down mode: 0.1 µA max.
Internal high-accuracy voltage detection circuit
A high voltage withstand device is used for charger connection pins

Internal three-step overcurrent detection circuit (overcurrent 1, overcurrent 2, and load short-circuiting)
Either the 0 V battery charging function or 0 V battery charge inhibiting function can be selected.
Products with and without a power-down function can be selected.

(PKG drawing code : MP005-A)
*1. Overcharge release voltage = Overcharge detection voltage - Overcharge hysteresis
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge 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.)
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.)

SOT-23-5, 5-Pin SON(A)
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.
