EnglishCXPR7145D product is a high integration solution for lithium-ion/polymer battery protection. contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuit
目录 1.产品概述 2.产品特点 一,产品概述(General Description) battery protection. detection circuits and delay circuits. CXPR7145D is put into an ultra-small DFN2X2-6 package and only one including overcharging, overdischarging, overcurrent and load short circuiting rotection 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. 二</span>.产品特点(Features)

NUMBER | PIN NAME | PIN DESCRIPTION |
1 | VDD | Power Supply |
2，3 | GND | Ground, connect the negative terminal of the battery to this pin |
4，5，6 | VM | The negative terminal of the battery pack. The internal FET switch |
7 | EPAD | Please connect EPAD with mass metal GND |
七</span>,功能概述
The CXPR7145D monitors the voltage and current of a battery and protects it from being damaged due to overcharge voltage,overdischarge voltage, overdischarge current, and short circuit conditions by disconnecting the battery from the load or charger. These functions are required in order to operate the battery cell within specified limits.
The device requires only one external capacitor. The MOSFET is integrated and its RDS(ON) is as low as 45mΩ typical.
