General Description

The MAX6782–MAX6790 are low-power, 1 accurate, dual-/triple-/quad-level battery monitors offered in small TDFN and TQFN packages. These devices are ideal for monitoring single lithium-ion (Li+) cells, or multicell alkaline/NiCd/NiMH power sources. These devices feature fixed and adjustable hysteresis options to eliminate output chattering associated with battery-voltage monitors.
