How shall be the impact of hysteresis value interpreted? Datasheet notes hysteresis of 0.55% (min 0.3%, max. 0.8%) plus a note: of nominal trip point. What does this exactly mean?
Example: TPS3702CX33 +/-4% nominal thresholds, +/-0.9% threshold accuracy results into a threshold band of +/-3.1 to +/-4.9%. In order to switch back from trip point there is the hysteresis, lets use the extreme value 0.8%. If I understand the note correctly the absolute value of hysteresis is for overvoltage (OV): 3.3V*(1+4%)*0.55% =18.876mV and for undervoltage (OV): 3.3V*(1-4%)*0.55% = 17.424mV. So, this means different hysteresis values. Did I got it right? In the TPS3702 decoder calculation spread sheet the hysteresis extreme value of 0.8% is referred to the nominal threshold surplus the threshold accuracy. Is this correct?
