CN305
Overview CN305 is a window comparator integrated circuit with independent overvoltage and undervoltage output terminals. It includes two comparators and a voltage reference source, and is particularly suitable for voltage detection of single or multiple lithium batteries, multiple alkaline batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and multiple lead-acid batteries. CN305 detects voltage thresholds with an accuracy of ±2%, and the comparator hysteresis is 7.5%. The hysteresis can eliminate detection output disturbances caused by disturbances in the detected voltage or voltage instability due to load changes. CN305 has two input terminals, both of which can be set to detect voltage through an external resistor divider network. When the OVIN pin voltage rises above the OVIN rising threshold, the pin outputs a low level; when the UVIN pin voltage drops below the UVIN falling threshold, the pin outputs a low level. The typical static operating current of CN305 is 11uA, and the output type is open-drain output. CN305 uses a 6-pin SOT23 package and operates in an ambient temperature range of -40°C ~ +85°C.
