EC9522T - LI-ION PROTECTION IC

This page provides the datasheet information for the EC9522T, a member of the EC9522T_E LI-ION PROTECTION IC family.

Datasheet Summary

Description

The EC9522T is protection IC for over-charge/discharge of rechargeable one-cell Lithium-ion(Li+) excess load current, further include a short circuit protector for preventing large external short circuit current.

Features

  • Low supply current High accuracy detector Threshold Supply current Standby current (after detecting over-discharge) Over-charge detector(Topt=25ºC) Over-charge detector (Topt=0 to 50ºC) Over-discharge detector Variety of detector threshold Built in protection circuit Output delay of over charge Output delay of over-discharg Small package Note1: The result was measured from EC9522T0001 Over-charge detector threshold Over-discharge detector threshold Excess current protection Accuracy Time delay a.
