特点:

  • high precision voltage detection(vsa = 4.20v ± 2.5%).
  • internal reset circuit that user selectable thresholdlevel with hysteresis (vsb = 1.230v ± 1.5%). internal open collector output comparators to create over voltage detection circuit, reference voltage generator, and more. (vsc,outc)
  • user selectable delay time of releasing reset signal depending on capacitor of ct node.
  • low power dissipation (icc = 0.35ma ,vcc = 5v).
  • sop8 package (5.0×6.2mm, 1.27mm pitch).
