Power-up Sequence
Maximum Rise Rate
Minimum Rise Rate
Figure 6-2.
To avoid risk of latch-up, the rise rate of the power supplies must not exceed the values
described in
Recommended order for power supplies is also described in this table.
The integrated Power-Reset circuitry monitoring the powering supply requires a minimum rise
rate for the VDDIN_5 power supply.
See
If the application can not ensure that the minimum rise rate condition for the VDDIN power sup-
ply is met, the following configuration can be used:
• A logic “0” value is applied during power-up on pin RESET_N until:

– VDDIN_5 rises above 4.5V in 5V single supply mode.
– VDDIN_33 rises above 3V in 3.3V single supply mode.
