Tool/software:
Hi,
I am looking to use the LM74502 as a load switch to power one of my devices, the IC works well I just had a question on a specific scenario that can happen.
The LM74502 will not be connected to back to back mosfets we will be just using one mosfet. The scenario is sometimes there can be reverse current flow through the external mosfet's body diode while the device is disabled. Image below describing the scenario
Meaning SRC pin will be providing voltage to VS pin via the body diode. This will mean that SRC pin will have 1V higher than VS to allow the current to conduct through the body diode
The voltage will be at most 30V applied to SRC pin which means VS would be 29V
On the data sheet it states that Abs Max SRC to GND is up to VS
But then in recommended conditions it states SRC to GND is 60V
Would be great to know if you see this as an issue that could damage the device
Thanks,
