The analog output VPROPI varies proportionally with the SENSE voltage according to Equation 2. It’s important to note even if VSENSE is negative VPROPI will remain at 0 V.
An RC network in series with the VPROPI output is recommended, if this voltage is to be sampled by an analog to digital converter.
It is imperative to realize that VPROPI will decrease to 0 V while the H-Bridge enters slow decay recirculation.
