  ...This is a protection IC for one-cell series that protects lithium ion batteries during excess charging,discharging, or overcurrent. If abnormalities occur during charging and excess voltage is applied, it has afunction that turns off the external FET switch when voltage is applied to each battery beyond a specified time(overcharging detection). It also has a function that turns off the external FET switch when the voltage for...
  ...detection). At that time, the IC is switched to low current consumption mode. Also, when there is a largecurrent flow due to shorting or other reasons, there is a functions for turning off the external FET switch(overcurrent detection). These function comprise a protection circuit, with few external parts, for lithium ionbatteries....
