... SC70 packages. These low-power devices are ideal for monitoring single lithi- um-ion (Li+) cells, or multicell alkaline/NiCd/NiMH power sources. These devices offer single (MAX6775/ MAX6776/MAX6777/MAX6778) or dual (MAX6779/ MAX6780/MAX6781) low-battery outputs and feature fixed or resistor-adjustable hysteresis. Hysteresis elimi- ...

... Hysteresis removes, or greatly reduces, the possibility of the output changing state in response to noise or battery terminal voltage recovery after load removal. The MAX6775/MAX6776/MAX6779/MAX6780/MAX6781 have factory-set hysteresis for ease of use, and reduce component count. For these devices, the absolute hys- teresis voltage is a percentage of the internally generat- ed reference. The amount depends on the device option. “ ...
