according to the datasheet of ADAS3023 the power sequence must be as following (page 24):
There is a schematic on page 21 (Figure 38) where AVDD, DVDD and VIO coming up together since all those voltages connected to 5V.
1.If it’s allowed that AVDD, DVDD and VIO appear together (Figure 38), what is the right time for VDDH and VSSH than? Before or after?
2.As I see in figure 38 both voltages (VDDH and VSSH) appearing simultaneously. Is it allowed for those both voltages?
Many thanks in advance.
