The MAX6782–MAX6790 are low-power, 1% accurate,dual-/triple-/quad-level battery monitors offered in smallTDFN and TQFN packages. These devices are ideal formonitoring single lithium-ion (Li+) cells, or multicell alkaline/NiCd/NiMH power sources. These devices featurefixed and adjustable hysteresis options to eliminate outputchattering associated with battery-voltage monitors.The MAX6782/MAX6783 offer four battery monitors in asingle package with factory-set (0.5%, 5%, 10%) oradjustable hysteresis. The MAX6784/MAX6785 providethree battery monitors with factory-set (0.5%, 5%, 10%)or adjustable hysteresis. The MAX6786/MAX6787/MAX6788 offer two battery monitors with external inputsfor setting the rising and falling thresholds, allowingexternal hysteresis control. The MAX6789/MAX6790 featurequad-level overvoltage detectors with complementaryoutputs.The MAX6782–MAX6790 are offered with either open-drainor push-pull outputs. The MAX6782/MAX6784/MAX6786/MAX6789 are available with push-pull outputs while theMAX6783/MAX6785/MAX6787/MAX6790 are available withopen-drain outputs. The MAX6788 is available with oneopen-drain output and one push-pull output (see theSelector Guide). This family of devices is offered in spacesavingTDFN and TQFN packages and is fully specifiedover the -40°C to +85°C extended temperature range 1% Accurate Threshold Specified Over FullTemperature Range Dual-/Triple-/Quad, Low-Battery Output Options Low 5.7μA Battery Current Open-Drain or Push-Pull Outputs Fixed or Adjustable Hysteresis Low Input Bias Current Guaranteed Valid Low-Battery-Output Logic StateDown to VBATT = 1.05V Reverse-Battery Protection Immune to Short Battery Transients Fully Specified from -40°C to +85°C Small TDFN and TQFN Packages
