CONSONANCE
Low Power Window Detector
General Description
The CN305 is a single adjustable window detector with separate under/overvoltage outputs. It consists of 2 parators and a voltage reference, and is specially designed for monitoring single or multi lithium-ion (Li+) cells, multi-cell alkaline,
Ni Cd, Ni MH and multi-cell lead acid batteries.
The parators’ 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 divider. When the voltage at OVIN rises above the rising overvoltage threshold, goes low. When the voltage at UVIN falls below the falling under voltage threshold, is driven to low.
The device has a low quiescent current of 11u A typical, and offers open-drain outputs.
