PBD 3517/1

Diagrams
How to use the diagrams:
1.
What is the maximum motor current
in the application
The ambient temperature sets the
maximum allowable power
dissipation in the IC, which
relates to the motor currents and
the duty cycle of the bilevel
function. For PBD 3517/1, without
any measures taken to reduce
the chip temperature via
heatsinks, the power dissipation
vs. temperature follows the curve
in figure 4.
Figures 9 and 10 give the
relationship between motor
currents and their dissipations.
The sum of these power dissipa-
tions must never exceed the
previously-established value, or
life expectancy will be drastically
shortened.
When no bilevel or voltage
doubling is utilized, the maximum
motor current can be found
directly in figure 9.
2.
How to choose timing components.
Figure 7 shows the relationship
between C
, R
, and t
. Care
must be taken to keep the t
time
short, otherwise the current in the
winding will rise to a value many
times the rated current, causing
an overheated IC or motor.
3.
What is the maximum t
On
pulse-width
at a given frequency
Figure 8 shows the relationship
between duty cycle, pulse width,
and step frequency. Check
specifications for the valid
operating area.
4.
Figures 4, 5 and 6 show typical
saturation voltages vs. output current
levels for different output transistors.
5.
Shaded areas represent operating
conditions outside the safe operating
area.
