... A +1.6V to +5.5V single-supply operating voltage range makes the MAX965 family of comparators ideal for 2-cell battery-powered applications. The MAX965/MAX967/ MAX968/MAX969 offer programmable hysteresis and an internal 1.235V ±1.5% reference. All devices are available in either space-saving 8-pin µMAX QSOP packages. ...

... The dual MAX968 is similar to the MAX967, but is configured as a window comparator. The MAX969 is a quad com- parator with a common hysteresis adjustment and a ref- erence output pin. The MAX970 is a quad comparator without a reference and without hysteresis adjustment ...

... The MAX965–MAX970 have internal hysteresis to counter parasitic effects and noise. In addition, with the use of external resistor, the MAX965/MAX967/ MAX968/MAX969’s hysteresis can be programmed to as much as ±50mV (see the section Adding Hysteresis to the MAX965/MAX967/MAX968/MAX969). The hysteresis in a comparator creates two trip points: one for the rising input voltage and one for the falling input voltage (Figure 2) ...

... Adding Hysteresis to the MAX965/MAX967/MAX968/MAX969 To add hysteresis to the MAX965/MAX967/MAX968/ MAX969, connect resistor R1 between REF and HYST, and connect resistor R2 between HYST and GND (Figure 3). If additional hysteresis is not required, connect HYST to REF. When hysteresis is added, the upper and lower trip points change by the same amount in opposite directions ...
