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.

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. The MAX6786/MAX6787/MAX6788 offer two battery monitors with external inputs for setting the rising and falling thresholds, allowing external hysteresis control. The MAX6789/MAX6790 feature quad-level overvoltage detectors with complementary outputs.

The MAX6782–MAX6790 are offered with either open-drain or push-pull outputs. The MAX6782/MAX6784/MAX6786/MAX6789 are available with push-pull outputs while the MAX6783/MAX6785/MAX6787/MAX6790 are available with open-drain outputs. The MAX6788 is available with one open-drain output and one push-pull output (see the Selector Guide in the full data sheet). This family of devices is offered in space-saving TDFN and TQFN packages and is fully specified over the -40°C to +85°C extended temperature range.
