APPLICATION NOTES

Figure 5. Typical Application Circuit Diagram

For higher current driving capability two outputs of the same kind can be paralleled. In this case the maximum

flyback energy should not exceed the limit value for single output.

The immunity of the circuit with respect to the transients at the output is verified during the characterization for

Test Pulses 1, 2 and 3a, 3b, DIN40839 or ISO7637 part 3. The Test Pulses are coupled to the outputs with

200pF series capacitor. All outputs withstand testpulses without damage.

The correct function of the circuit with the Test Pulses coupled to the outputs is verified during the characteriza-

tion for the typical application with R = 16W to 200W, L= 0 to 600mH loads. The Test Pulses are coupled to the

outputs with 200pF series capacitor.
