Other Parts Discussed in Thread: UCD90124
Hi Team,
My customer asked the following question on getting started with the UCD90160A:
The eval I got had a ucd90124, and I replaced it with ucd90160a because its what I placed in my prototype.
Before I program my proto board, I wanted to use the eval and see how it works. I have many rails to power sequence and also to monitor.
But for starters, if you could provide me an example in how to do the following.
For example, I have a Vin=5V, and two LDOs to convert 5V in to 3.3V and 1.8V. I want to sequence 3.3V to turn on first until pgood and then enable the 1.8V LDO.
So How do I build a new system? Say I want to use mon1 to monitor 5Vin. As soon as its about >90% 5V, I want to use an GPO 1 to enable 3.3V LDO.
Next, once the 3.3V LDO is good then feed this signal to Mon2 I guess and then use GPO2 to enable 1.8V LDO.
And then monitor the health of 3.3V and 1.8Vs.
Thanks,
JP
