EC9529A数据手册E-CMOS中文资料规格书

描述 Description

The EC9529A series is a highly integrated solution for lithium- ion/polymer battery protection. It contains advanced power MOSFET,  high-accuracy  voltage  detection  circuits  and  delay  circuits. EC9529A is  performed  in  ultra-  compact  SOT23-5 package  and  only  one  external component required, making  it an  ideal solution  in  limited  space  of  battery  pack. EC9529A has all the protection functions required in the battery application including over- charging, over- discharging, over-current and  load  short  circuiting  protection  etc.  The  accurate  over-  charging  detection  voltage  ensures  safe  and  full  utilization charging.  The  low  stand-  by  current  drains  little  current  from  the  cell  while  storage.  The  device  is  not  only  targeting digital  cellular  phones,  but  also  for  any  other  Li-Ion  and  Li-Poly  battery-powered  information  appliances  requiring  long- term battery life
