Duration of the pauses
The maximum allowable dissipated power P is then
0.77 W during the motor active periods in the event of a
DIP8 package being used. Dissipation pulses due to
starting and stopping the motor can be ignored because of
their short duration. This maximum allowable dissipated
power implies that the maximum continuous motor current
(
I
m) is approximately 250 mA during the motor active
periods when the supply voltage VP is 13 V. The maximum
allowable dissipated power P is 0.67 W during the motor
active periods in the event of a SO16 package being used.
This implies that the maximum continuous motor current
(
I
m) is approximately 220 mA during the motor active
periods when the supply voltage (VP) is 13 V.

Stereo operation
The default application will be when two modules are
driven by one set potentiometer. One module controls the
left head light, where the other one controls the right head
light. Each module is connected by three wires: the battery
line, the ground line and the set input wire. This can result
in two additional fault conditions: from one module the
battery line or the ground line can be broken, when the
other module is still connected. Assume that the left one
operates normally, where the right one has a fault. The
setting potentiometer will have extra loading when the
battery line is broken. This will result in a lower voltage at
the wiper of the setting potentiometer. Thus the left module
will start to regulate until a new equilibrium is reached.
The amount of extra loading can be influenced by the
external series resistor in the set input. These fault
conditions and their implications should be considered
when the total application is designed.
Test diagram
All parameters in chapter “Characteristics” until this
section are measured at Tamb = 25 °C and are tested at
each device using the test set-up of Fig.12. The only
exceptions are parameters supply current (motor active)
and output voltage (motor output) where the 1 k
output
resistor is replaced by an appropriate current source.
