CN312
Overview CN312 is an ultra-low power voltage detection chip with adjustable hysteresis, especially 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. The upper threshold and lower threshold of CN312 can be set independently for easy hysteresis setting. When the monitored voltage is lower than the lower threshold, the pin output of CN312 is low, and the LBO pin output is high; when the monitored voltage is higher than the upper threshold for a duration exceeding the delay tD (minimum 25 milliseconds), the pin output of CN312 is high, and the LBO pin output is low. The voltage difference between the lower threshold and the upper threshold is the hysteresis. Hysteresis can eliminate the detection output disorder caused by the noise of the detected power supply or the instability of the battery voltage due to load changes. CN312 uses a 6-pin SOT23 package and operates in an ambient temperature range of -40°C ~ +85°C.
