I am using an Infineon ITS4200S-SJ-D highside switch to control power to a resistive load. Internally the part is basically a PFET with some additional features.
I have a 10k pulldown on pin 2, +12V on pin 5, and a 100ohm resistive load on pin 3.
Everything works great except I notice that if I connect the load and the +12V before I connect the GND I get a leakage current to the load.
I know that the simple answer is "always connect the GND cable first." But I'm wondering if someone can give me an idea for a simple circuit that I can add to prevent this leakage and keep the load totally un-powered until both of the power supply cables are connected correctly and I activate the input at pin 2.
Here is the schematic. for troubleshooting I have disconnected the microcontroller activation line as indicated by the little red X. The problem I'm trying to solve is when the +12V cable is connected and the GND cable is unconnected I see about 15mA through the load.
