Pin Description
17
RD
Motor constrained state detection output
(This is an open-collector output.)
When the motor is constrained: high, when the motor is
turning: low.
VREG
Equivalent Circuit
17
18
PWM
PWM pulse input.
IN
When low the output will be on and when high the
outputs will be off. If this pin is used to control this IC,
connect EI- to ground and connect EI+ to TOC.
VREG
