Hello our current design has a PTN78020W which has two breaker relays that control the sense line and power line. We recently had an issue wear the fuse blew in the power-line and due to design limitations the sense line didn't break its connection. This caused the sense line to supply power to the UUT (through the 10 ohm internal resistor). We are trying to find a way to avoid drawing current through the sense port and causing issues with the device.
