Channel E
Not Sequenced; Sequence Position null (7);
Over-voltage; Programmable Threshold(V
PTHE
) =
3.64V
Channel F
Not Sequenced; Sequence Position null (7);
Over-voltage; Programmable Threshold(V
PTHF
) =
1.34V
Power-Off in reverse order
RST_A# triggered by channels C, D, E, and F; cleared
on PUPB active
RST_B# triggered by channels B, D, E, and F
IRQ# triggered by channel A
VCCA, VCCB, and VCCC selected as precursors to
power-on sequencing
The resulting timing diagram is shown in Figures 9
and 10. Figure 9 shows the SMS64 sequencing the
supplies on and then monitoring for fault conditions.
Figure 10 shows the SMS64 sequencing the supplies
off then sequencing the supplies on.
