Part Number:UC2625
Hello,
I am using the UC2625 and from what I understood in the datasheet and the block diagram is that once SPEED-IN passes a certain threshold, which should be around 250mV, the device should inhibit any change in direction. In my application I have my inputs setup for Pin 12 (PDC) to be high while Pins 13 and 14 (PDB & PDA) are low. When I set SPEED-IN to the max threshold which should insure no change in direction and change the DIR pin from a 1 to a 0 with no change in my other inputs setup I see a change in my outputs (PDC goes low, PDB goes high and PDA stays low). Shouldn't the outputs not change since SPEED-IN is above the threshold that should inhibit any changes in DIR? Or is there something I am missing ?
Thank You,
Youssef
