The detection cancellation voltage combines the detection voltage VDET with the hysteresis voltage. If the voltage of the measurement sample is VDET, the additional voltage variation hysteresis voltage ΔVDET acts as the detection cancellation voltage. For the BU42/43 series, VDETx0.03 is the minimum, VDETx0.05 is standard, and VDETx0.07 is the max. In addition, there is a 1% tolerance with VDET. As an example for a VDET of 3.4, the minimum hysteresis voltage would be 3.366x0.03=0.101V and the max. 3.434x0.07=0.2404V.
