... These devices feature fixed and adjustable hysteresis options to eliminate out- put chattering associated with battery-voltage monitors. The MAX6782/MAX6783 offer four battery monitors in a single package with factory-set (0.5%, 5%, 10%) or adjustable hysteresis. The MAX6784/MAX6785 provide three battery monitors with factory-set (0.5%, 5%, 10%) or adjustable hysteresis ...
