FUNCTIONAL DESCRIPTION
Motor pulse
The motor driver delivers pulses with an alternating
polarity. The output waveform across the motor terminals
is illustrated in Fig.4. Between the motor pulses, both
terminals are connected to V
DD
which means that the
motor is short-circuited.
The following parameters can be selected and are stored
in a One Time Programmable (OTP) memory:
Output periods of 1 s, 5 s, 10 s, 20 s and 30 s
Pulse width (t
p
) between 0.98 ms and 7.8 ms in steps of
0.98 ms
Full or chopped (75 %) output pulse
Pulse stretching: an enlargement pulse is added to the
primary motor pulse. This enlargement pulse has a duty
cycle of 25 % and a width which is twice the
programmed motor pulse width.
