there is a request in my design that hysteresis of por is 0.07v, what does it mean,is it means delay is 0.07v? what is the use of hysteresis in por ?
thanks
Mainly the POR hysteresis is used to absorve the variation of the power supply during the power on phase, you will have a threshold value in order to compare to resetout the processor (the power supply is now in stady state) and this comparison has and hysteresis in order to absorve the variation/ripple of the power supply.
Hystersis of 75mV means that, when your input goes above threshold by 75mV then only the ouput would go high. Similarly, when input is going down , the output shall chage only when input has gone 75mV below the threshold vlaue
Hope it helps
