S-8241ABKMC-GBK - Brand New SE Battery Management ICs
-
Description
The S-8241ABKMC-GBK is a lithium-ion/lithium polymer battery protection IC for 1-cell packs. It incorporates high-accuracy voltage detection circuits and delay circuits for overcharge, overdischarge, and overcurrent protection. This IC is suitable for protecting 1-cell lithium-ion/lithium polymer battery packs.
Specifications and features
(1) Internal high-accuracy voltage detection circuit: The overcharge detection voltage range is 3.9 to 4.4 V with an accuracy of ±25 mV(+25 °C) and ±30 mV(−5 to +55 °C). The overcharge release voltage range is 3.8 to 4.4 V with an accuracy of ±50 mV. The overdischarge detection voltage range is 2.0 to 3.0 V with an accuracy of ±80 mV. The overdischarge release voltage range is 2.0 to 3.4 V with an accuracy of ±100 mV. The overcurrent 1 detection voltage range is 0.05 to 0.3 V with an accuracy of ±20 mV. The overcurrent 2 detection voltage is fixed at 0.5 V with an 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 are generated by an internal circuit, eliminating the need for external capacitors. The accuracy of delay times (overcharge, overdischarge, overcurrent 1, and overcurrent 2) is ±30%.
(4) Internal three-step overcurrent detection circuit for overcurrent 1, overcurrent 2, and load short-circuiting.
(5) Selectable 0 V battery charging function or 0 V battery charge inhibiting function.
(6) Power-down function can be selected.
(7) Charger detection function and abnormal charge current detection function. The overdischarge hysteresis is released by detecting a negative VM pin voltage. If the output voltage at DO pin is high and the VM pin voltage becomes equal to or lower than the charger detection voltage, the output voltage at CO pin goes low.
(8) Low current consumption: 3.0 μA typ. 5.0 μA max. in operation and 0.1 μA max. in power-down mode.
(9) Wide operating temperature range: -40 to +85 °C.
(10) Small package options: SOT-23-5, SNT-6A.
(11) Lead-free products.Application Scenarios
The S-8241ABKMC-GBK is ideal for use in lithium-ion and lithium-polymer rechargeable battery packs.
