Hello,
we have a circuit that we want to supply from 2 different power supplies (never from both simultaneously). We have planned to use the depicted scheme.
- If power supply A is present, we supply some HW (that is not depicted on image) directly from PSA, and through the load switch we also supply the load that is on the right side of load switch.
- If power supply B is present, we want to supply only load that is on the right side of load switch. The load switch would be switched off.
The question is: Can we cause any damage to the load switch if PowerSupplyA is not present and Power Supply B is present? I have read that there ir an internal discharging resistor on output, would it be continuosly dissipating energy? or if Vin is not supplied the load resistor isn't present?
