APPLICATIONS INFORMATION
The typical application diagram for parallel Input SPI control is shown in Figure 4.
Figure 4. Typical Application Circuit Diagram for the L9823 Circuit.
For higher current driving capability more 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. 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 = 16
to 200
, L= 0 to 600mH loads. All outputs
withstand testpulses without damage.
