MAX835:微功耗、具有锁存功能的电压监测器,SOT23-5封装

业内唯一的SOT封装电压监控电路,带锁存输出

The MAX834/MAX835 micropower voltage monitors contain a 1.204V precision bandgap reference, comparator, and latched output in a 5-pin SOT23 package. Using the latched output prevents deep discharge of batteries. The MAX834 has an open-drain, n-channel output driver, while the MAX835 has a push-pull output driver. Two external resistors set the trip-threshold voltage. The MAX834/MAX835 feature a level-sensitive latch, eliminating the need to add hysteresis to prevent oscillations in battery-load-disconnect applications.
