Power-On Reset Timing
Table 10-2
lists typical ICS1531 power-on reset (POR) timing measures and
Figure 10-4
shows the POR
timing relationships. (For information on how the ICS1531 POR circuitry operates, see
Section 8.2, “Power
Considerations”
.)
If a reset:
Is desired, reduce the VDD supply voltage (and the voltage on all ICS1531 pins) so that it is below the
threshold voltage (VDD
th
) of the POR circuit for the period t1. (A time of 10 ms is sufficient.)
Is not desired, ensure either one or both of the following conditions:
– Ensure the VDD supply voltage (and the voltage on all ICS1531 pins) is not reduced below V
min
.
– If the VDD supply voltage (and the voltage on all ICS1531 pins) is reduced below V
th
, then ensure
that it is at this level for less than the period t1.
Note:
The POR signal is an internal signal. It is generated regardless of the ICS1531 mode.
