AF5918中文资料One Cell Lithium-ion/Polymer Battery Protection IC数据手册AF规格书

描述 Description

The AF5918 battery protection IC is designed to protect lithium-ion/polymer battery from damage or degrading the lifetime due to overcharge, overdischarge, and/or overcurrent for one-cell lithium-ion/polymer battery powered systems, such as cellular phones.

The ultra-small package and less required external components make it ideal to integrate the AF5918 into the limited space of battery pack. The accurate ±50mV overcharging detection voltage ensures safe and full utilization charging. The very low standby current drains little current from the cell while in storage.

特性 Features

• Reduction in Board Size due to Miniature Package SOT23-6.
• Ultra-Low Power-Down Current at 0. 2μA (Vcc=2.0V).
• Load Detection Function during Overcharge Mode.
• Delay times are generated by internal circuits.
• No external capacitors required.
