Definition of Rise and Fall Time

PWM Current Interface

Between each magnetic transition and the rising edge of the corresponding output pulse

the output current is Low for

t

Following the signal pulse (current is High) is output.

5) not subject to production test- verified by design/characterization, magnetic values are amplitude values
