R5449 one-cell Li-ion / Polymer Battery Protection IC

The R5449 is one-cell Li-ion / polymer battery protection IC that provides overcharge, over-discharge, discharge/charge overcurrent, and temperature detections. The IC can drive external high-side Nch MOSFETs and provides a high-accuracy detection at overcharge and overcurrent, and a high-accuracy charge inhibition for 0V battery. Furthermore, the IC can reduce the supply current after over-discharge detection to a minimum by stopping the internal circuits and the CTL pin can forcefully enter the IC into standby mode.

The applications of the product are Li+ / Li- polymer protector of overcharge, over-discharge, and overcurrent for the battery pack and, High precision protectors for smartphones and any other electronic gadgets using on-board Li+ / Lipolymer battery. 

Features:

  • Absolute Maximum Rating is 6.5 V
  • Supply Current at Normal Mode Typ.5.0 µA
  • Standby Current Max.0.04 µA
