XB6536H_ _ _ _ _ _ _ _ _ One Cell Lithium-ion/Polymer Battery Protection IC GENERAL DESCRIPTION The XB6536H product is a high integration solution for lithium-ion/polymer battery protection.XB6536H contains advanced power MOSFET,high-accuracy voltage detection circuits and delay circuits.XB6536H is put into an ultra-small DFN2X2-6 package and only one external component makes it an ideal solution in limited space of battery pack.XB6536H 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.FEATURES Protection of Charger Reverse Connection Protection of Battery Cell Reverse Connection Integrate Advanced Power MOSFET with Equivalent of 35m RSS(ON)Ultra-small DFN2X2-6 Package Only One External Capacitor Required Over-temperature Protection Overcharge Current Protection Two-step Overcurrent Detection:-Overdischarge Current-Load Short Circuiting Charger Detection Function 0V Battery Charging Function-Delay Times are generated inside High-accuracy Voltage Detection Low Current Consumption-Operation Mode:2.8A typ.-Power-down Mode:1.5A typ.RoHS Compliant and Lead(Pb)Free APPLICATIONS One-Cell Lithium-ion

possible.For thermal management,ensure that these trace widths are adequate.C1 is a decoupling capacitor which should be placed as close as possible to XB6536H.Fig 6 XB6536H in a Typical Battery Protection Circuit Precautions Pay attention to the operating conditions for input/output voltage and load current so that thepower loss in XB6536H does not exceed the power dissipation of the package.Do not apply an electrostatic discharge to this XB6536H that exceeds the performance ratings of thebuilt-in electrostatic protection circuit.深圳市骊微电子科技有限公司XB6536H _ _ _ _ _ _ _PACKAGE OUTLINE
