      General Description
      The CN312 is an ultra-low power high accuracy battery monitor with hysteresis control, and is specially designed for monitoring single or multi lithium-ion (Li+) cells, multi-cell alkaline, NiCd, NiMH and multi-cell lead acid batteries.
      The CN312 allows for wide hysteresis by adjusting the rising and falling threshold independently. The threshold accuracy is 1%.
      If the monitored voltage is lower than the falling threshold, LBO pin becomes high and LBO- pin becomes low; If the monitored voltage is higher than the rising threshold, LBO pin becomes low and LBO- pin becomes high after a delay of tD.
      The hysteresis eliminates the output chatter sometimes associated with battery voltage monitors, usually due to input voltage noise or battery terminal voltage recovery after load removal.
      The device offers both active-low and active-high battery detection outputs.
      The device is available in 6 pin SOT23 package.
