Fig.7 Worst case transients on Vb (continued in Fig.8).
Worst case transients that may occur on the battery line Vb of the application (see Fig.10), are the pulses whose wave
forms and the corresponding values are as illustrated in Figs 7 and 8. The signal source which generates these pulses
(numbered pulses 1 and 2) has a series resistance (Ri) of 10 Ω. These pulses represent for instance the influence of
switching of inductors on the battery line. The signal source which generates pulses 3 and 4 has a series resistance of
50 Ω. These pulses represent for instance the influence of ignition on the battery line. Their repetition rate is 100 ms.
