RY2202 Description/概述：
The RY2202 is a high integration solution for lithium-ion/polymer battery protection. RY2202 contains internal power MOSFET, high-accuracy voltage detection circuits and delay circuits. RY2202 has all the protection functions required in the battery application including overcharging, over discharging, overcurrent and load short circuiting protection etc. The accurate overcharging detection voltage ensures safe and full utilization charging. The low standby current drains little current from the cell while in storage. The device is not only targeted for digital cellular phones, but also for any other Li-Ion and Li-Poly battery-powered information appliances requiring longterm battery life.
The RY2202 requires a minimal number of readily available, external components and is available in a space saving SOT23-6 package.
RY2202是一種針對鋰離子/聚合物電池保護的高集成解決方案。RY2202包含內(nèi)部電源MOSFET、高精度電壓檢測電路和延遲電路。RY2202具有電池應用中所需的所有保護功能，包括過充、過放電、過電流和負載短路保護等。準確的過充電檢測電壓保證安全充分充電。低備用電流在存儲期間從電池排出的電流很少。該設備不僅針對數(shù)字手機，還適用于任何其他需要長期電池壽命的鋰離子和鋰聚電池驅動的信息設備。
RY2202需要最少數(shù)量的現(xiàn)成的外部組件，并可在一個節(jié)省空間的SOT23-6軟件包中使用。
