R5461K series Li-ion/polymer 2Cell protector IC with alarm function
The R5461K Series are high voltage CMOS-based protection integrated circuits designed specifically for rechargeable two-cell Li-ion or Lithium polymer battery packs. These devices provide comprehensive protection against over-charge, over-discharge, excess discharge current, and excess charge current. Additionally, the series includes an alarm function that outputs a signal before detecting over-charge to allow for early warning.
