Sign/magnitude PWM consists of separate direction (sign)
and amplitude (magnitude) signals (see
solute) magnitude signal is duty-cycle modulated, and the
absence of a pulse signal (a continuous logic low level) rep-

resents zero drive. Current delivered to the load is propor-
tional to pulse width. For the LMD18201, the DIRECTION
input (pin 3) is driven by the sign signal and the PWM input
(pin 5) is driven by the magnitude signal.
