General Description
The CN301 is an ultra low power battery monitor, 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 device offers a single low-battery output and features fixed hysteresis. 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 is available in 5 pin SOT23 package and is fully specified over the -40°C to +85°C extended temperature range.
