HY2550

HY2550 Series Features
  • High-accuracy voltage detection circuit for 3/4/5 Cell Application
  • Charge overcurrent protection
  • Three-level discharge overcurrent protection
  • Delay time:
    • Delay times are set by external capacitors respectively at CCT pin and CDT pin for overcharge detection, /charge overcurrent detection and overdischarge detection/discharge overcurrent detection voltage 1
    • Delay times are set internally for discharge overcurrent detection voltage 2 (1ms) and discharge overcurrent detection 3 (300μs)
  • Cell number selection: SEL pin is used to select either 3 cells or 4 cells in use. SEL5 pin is used to select 5 cells in use when SEL pin is also set to “1”
  • Charge/discharge operation can be controlled via the CTL pin
  • 0V Battery Charge inhibition
  • High voltage withstand range: Absolute maximum rated level:28V
  • Wide operating temperature range:-40℃ to +85℃
  • Low current consumption:
    • Operation mode 12μA typ., 30μA max. (VCn = 3.5V)
    • Power-down mode 1.2μA typ., 2.0μA max. (VCn = 2.0V)
  • Small package:16-pin TSSOP
  • Halogen free green product
