HY2141

HY2141 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.
  • utput logic active high maximum time: (optional; not-limited as default)
  • Low current consumption
    • Operation mode 5.0μA typ., 9.0μA max. (VCelln = 4.15V)
    • OV detection OFF mode 4.5μA typ., 8.0μA max. (VCelln = 3.1V
    • LDO OFF mode 0.5μA typ., 1.0μA max. (VCelln = 2.0V)
    • Standby mode 0.5μA maximum. (VCelln=1.5V)
  • Selection of 2-cell/3-cell/4-cell application: either 2-cell or 3-cell or 4-cell is selectable by means of external circuit
  • LDO output circuit
    • LDO output voltage 3.3V Accuracy: ±65mV
    • LDO output current 2.5mA (maximum)
  • High voltage resistant design: the absolute maximum rated value is 30V.
  • Wide operating temperature range: -40℃ to +85℃
  • Small package: DFN-2.0*2.0-8L
  • Halogen free green product
