3130的5脚锂电池保护IC规格书.pdf

PW3130 Wuxi PWChip Semi Technology CO., LTD One Cell Lithium-ion/Polymer Battery Protection IC GENERAL DESCRIPTION The PW3130 series product is a high integration solution for lithium-lion/polymer battery protection.PW3130 contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits. PW3130 is put into an ultra-small SOT23-5 package and only one external component makes it an ideal solution in limited space of battery pack. PW3130 has all the protection functions required in the battery application including overcharging, overdischarging, 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 long-term battery life.
