4 Application information
The typical application diagram is shown in Figure 3.
Figure 3. Typical application circuit diagram
For higher current capability the two outputs of the same kind can be paralleled and the
maximum flyback energy should not exceed the limit for a single output.
The circuit immunity at output transients have been verified during the characterization with
Test Pulses 1, 2, 3a and 3b, DIN40839 or ISO7637 part 3.
The Test Pulses are coupled to the outputs with 200 pF series capacitor and all the outputs
are able to withstand to test pulses without damage. The load applied was in the range of 30
to 100 ohm for the resistive part and 0 to 600 mH for the inductive one.
