... 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. ...

... Comparator C Open-Drain Output tor configured as a dual voltage monitor with common hysteresis adjustment and a reference output. 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) ...
Page 10
... Hysteresis can be generated with three resistors using positive feedback (Figure 4). This method generally draws more current than the method using the HYST pin on the MAX965/MAX967/MAX968/ MAX969. Also, the positive feedback method slows hysteresis response time. Use the following procedure to calculate the resistor values: 1) Select R3 ...
