HY2131
Multi Cell Secondary Protectors

HY2131 Series Main Features
  • High-accuracy voltage detection circuit
  • Delay time is set by internal circuit (external capacitor is not needed)
  • Delay time shortening function: overcharge detection delay time can be
  • shortened by specific setup
  • Output logic: Active high CMOS output; the high level is 4.7V (typical)
  • output from regulator
  • Low current consumption:
    • Operation mode < 3.0μA typ., 6.0μA max. (VCelln =3.9V)
    • Standby mode < 0.5μA max. (VCelln = 3.1V)
  • Selection of 2-cell/3-cell application: either 2-cell or 3-cell is selectable by means of external circuit
  • High voltage resistant design: the absolute maximum rated value is 30V
  • Wide operating temperature range: -40℃~+85℃
  • Small package: TSOT-23-6, DFN6 (1.8X2.0mm)
  • Halogen free green product
