Hi,
Normally I would have just simulated the model instead of asking this, but as the SPICE model is not available I request to please review the schematic and confirm whether it will do what I intend to.
I have a device which works at either 15V or 24V and draws 30mA max current at 15V. The input supply decides the mode of operation of the device.
I am using TMUX6219 for switching between these two voltage levels.
LNB_SUPPLY_CTRL is the select line which is TTL logic. It will be either 0V or 5V.
When LNB_SUPPLY_CTRL is 0V, 24V supply should go out of the output Pin 1.
When LNB_SUPPLY_CTRL is 5V, 15V supply should go out of the output Pin1.
