Tool/software:
Hi all,
I am trying to use the following LM74800 based cct to select between 1 of 4 sources to then feed a load. The system is meant to support input voltages from 9-30v.
When powered and the mcu has selected an input by looking at the voltages on the voltage dividers, EN is set high (3.3v) and VBat1 is (in this case) 15v. I am only getting about ~6 on the output drain.
Any help appreciated.
The cct below is just 1 of 4.
