Other Parts Discussed in Thread: OMAPL138
Hello,
In our design using the OMAPL138, the 1.8V supply starts rising before the 3.3V supply. Because of this, the RESET signal to the OMAPL138 begins to rise and cross the Vinh threshold before the 3.3V increases enough to drive the POR. The RESET line would be "high" for about 120uS before POR. Is this OK for the OMAPL138 or should we try to modify the design?
Thanks in advance,
Eric
