Thermal aspects
The dissipation of the device is the sum of two sources:
the supply current (IP Im) times the supply voltage (VP)
plus the motor current (
I
m) times the output saturation
voltage (VP Vm). In formula:
(IP Im) is approximately equal to IP(ss) when the motor
is not running. It is obvious from the ratings that the
combination of VP = 18 V, (IP Im) = 80 mA,
I
m = 900 mA and (VP Vm) = 2.5 V can not be
allowed at Tamb = 105 °C; see chapter “Limiting values”
note 2. But it is also improbable that the motor is
continuously driven, therefore the following assumptions
have been made.

It is assumed that the device must be capable of moving
the motor from one end to the other in four equal steps and
that the total time needed for this excursion is 16 seconds.
After this excursion a pause is allowed before the same
pulses are used to return to the original position.
This operation is illustrated in Fig.11.
