Low Power, Dual-
Voltage Detector
CN303
General Description
The CN303 is a two-channel
voltage detector with 2 low power high accuracy comparators, 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 CN303’s 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 CN303 has 2 inputs that can be configured by the external resistor divider.
When the
voltage at IN1(IN2) rises above the rising threshold, ...
