Application Information
The typical application diagram is shown in
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 characterization for the typical application with R = 30Ω to 100Ω, L= 0 to 600mH loads. The
Test Pulses are coupled to the outputs with 200pF series capacitor.
