Battery Management ICs

  One-cell Li-ion/Polymer battery protection IC that is suitable for smart phone and tablet PC applications
  Main Features of HY2115 Series:  
  Provide high precision overcurrent detection when used with current sense resistance
  Built-in high precision voltage detection circuit and delay circuit
  High precision charge/discharge overcurrent detection voltage is flexibly configurable
  Low current consumption: Operation mode < 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
  Auto overdischarge recovery function “Yes” or “No” is selectable
  Tiny package: DFN(1.4mm*1.4mm)/SOT-23-6
  Wide operation temperature range: -40℃ to +85℃
  All products are in Green packages: Pb & Halogen- free
