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, OUT1(OUT2) goes high; When the voltage at IN1(IN2) falls below the falling threshold, OUT1(OUT2) is driven to low.
The device has a low quiescent current of 11uA typical, and offers CMOS outputs.
The device is available in 6 pin SOT23 package.
