CN302
Overview CN302 is a low-power battery 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 CN302 can be set independently for easy hysteresis setting. When the battery voltage is lower than the set lower threshold, the CN302 pin outputs a low level, and the LBO pin outputs a high level; when the battery voltage is higher than the upper threshold, the CN302 pin outputs a high level, and the LBO pin outputs a low level. The voltage difference between the lower threshold and the upper threshold is the hysteresis. Hysteresis can eliminate the detection output disorder caused by the instability of the battery voltage due to the noise of the detected power supply or the sudden change of the load. CN302 uses a 6-pin SOT23 package and has an operating temperature range of -40°C ~ +85°C.
