Other Parts Discussed in Thread: LM5050-1, LM5050-2
I am using LM5050-1 as Oring- Controller to select the primary source ( If both redundant and primary power source is available) or redundant power source (If Primary power source is not available). The Schematic is attached below for your reference. The OR-ing controller of redundant power supply (12V_EXT) shall be turned off via a voltage divider, which is pulled high to 12V0 (primary source). When the primary power (12V0) is available and redundant power source(12V_EXT) is not present, Able to see 2V at IN and GATE pin of redundant supply OR-ing controller. Able to see 2V at IN and GATE pin of primary supply OR-ing controller, when Primary source is not available and redundant power supply is fed. When both power sources are available, Primary power supply will source the load, as the redundant OR-ing controller will turn OFF the Mosfet. Kindly reply regarding the 2V leakage at IN and GATE pin of Mosfet
