B) Repetition mode
The turn ON diagnostic acquisition time is determined by the ripple filter capacitance C2 and
the equivalent internal resistance Rr as below expression.
Acquisition time
= 2 × C2 × Rr = 4400 × C2 (typ.)
Rr is fixed in internal circuit and it is not varied by the fluctuation of power supply VCC voltage.
C2 value determines the time from power ON (standby off) to the appearance of sound signal
from output and the characteristic for ripple rejection ratio, too. So, take care with the decision on
C2 value.
If the turn ON diagnosis is not used, in other words the diagnostic cycle defeat command is sent,
the waveform of ripple terminal voltage will change but the time from turning on to the output
signal appearance will not change as illustrated below in Figure 6.
