1 Features

  • 2-series, 3-series, and 4-series
    cell overvoltage protection (OVP)
  • Factory programmed OVP threshold (3.6V to 5.2V) with ±12mV accuracy
  • Fixed delay timer to trigger FET drive output
    (0.25s to 6.5s options)
  • Output pin options:
    • Active high
    • Open-drain - active pulldown
    • Open-drain - inactive pulldown
  • Integrated 3mA regulated output programmable to 3.8V, 3.3V, 3.15V, 3.0V, 2.5V, 1.8V, or 1.5V
  • Factory programmed undervoltage (UV) detection threshold (1V to 4.15V) to disable regulator
    • OVP remains operational even in undervoltage condition
  • Multiple power modes:
    • NORMAL mode - no OV or UV: ICC ≅ 1.23µA
    • Undervoltage mode - UV detected: ICC ≅ 0.25µA
    • Overvoltage mode - OV detected: ICC ≅ 19µA
  • Low leakage current per cell input < 100nA
  • Small package footprint
    • 8-Pin WSON (2mm × 2mm)
