Low Power Window Detector
CN305
General Description
The CN305 is a single adjustable window detector
with separate under/over
voltage outputs.
It
consists of 2 comparators and a
voltage reference,
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 comparators’ threshold accuracy is ±2%, and
offers 7.
5% hysteresis which 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 CN305 has 2 inputs that can be
configured by the external resistor divid...
