Typical Application Circuits
The load conditions at Q depend on the permissible power dissipation of the used power
transistors. The pulsed power dissipation in case of a short circuit must be observed.
In order to suppress oscillations of the power stage in case of a short circuit, a capacitor
C
at Q1 to Q4 is necessary if e.g. fast switching transistors are used.
Typical value X of
C
: approx. 20 nF.
The output circuit 1 is suited for currents up to approx.
I
Q
= 100 mA.
The output circuit 2 and 3 are suited for currents up to approx.
I
Q
= 2 A. A minimum
power dissipation can be achieved with circuit 3.
A break key in parallel to
C
T
allows a manual switch-on in case of short-circuit.
R
P
= Precision resistor (current measurement)
C
T
= 0.8 x
t
p
(nF,
μ
s)
t
p
= Short-circuit current pulse length
Note:
Circuit 1 does not permit a capacitor between Q1 and Q4 and the collector.
Circuit 2 does not permit a capacitor between Q1 and Q4 and base or emitter,
respectively.
Otherwise too high current spikes would arise in case of a short circuit.
