Battery Management ICs

  One-Cell Li-ion/Polymer/LiFePO4 Battery Protection
  Main Features of HY2110, HY2111 & HY2112 Series:  
  Built-in high precision voltage detection circuit and delay circuit
  Low current consumption:
        Operation mode<6μA (VDD=3.9V)<6μA (VDD=3.9V)
        Sleep mode<0.1μA (VDD=2.0V)
  Charger connected pin adopts high-withstand-voltage design(CS/OC pin absolute max. rating: 20V)
  0V battery charge function:“Available” or “Unavailable” is optional
  Small package: SOT-23-6
  Wide operation temperature range: -40℃ to +85℃
  All products are in Green packages: Pb & Halogen- free
  Product quality ensures customer production defect rate <50ppm
 
  Applications:  

  1-cell lithium-ion rechargeable battery packs
  1-cell lithium polymer rechargeable battery packs
  1-cell LiFePO4 rechargeable battery packs
