General Description

The CN302 is an 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 CN302 allows for wide hysteresis by adjusting the rising and falling threshold independently. The threshold accuracy is ±2%. 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.
