These devices are ideal for monitoring single lithium-ion (Li+) cells, or multicell alka- line/NiCd/NiMH power sources. 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. 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 fea- ture quad-level overvoltage detectors with complemen- tary 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). 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. Ordering Information Selector Guide Applications Ordering Information continued at end of data sheet. + Denotes lead-free package. * EP = Exposed paddle. The MAX6782/MAX6783/MAX6784/MAX6785 are available with factory-trimmed hysteresis. Specify trim by replacing “_” with “A” for 0.5%, “B” for 5%, or “C” for 10% hysteresis.
