power supply short circuit protection schematic
I am building a RS485 network with 4 lines. Data lines A ,B, V+ power and GND ground. The electronic circuit breaker post lead me to an EDN article that got me thinking about providing short circuit protection on the V+ line. This would protect the circuit when I add or remove devices from the active bus (Hot swap boards).
The problem is that the article Current limit protects power bus https://www.edn.com/archives/1997/121897/26di_07.htm is ten years old and the schematic resolution is too low to make out many of the parts numbers or values.
I looked for "short circuit portection" via google and for parts on Mouser but did not find anything quite like it.
I can look further but perhaps someone here has a helpful suggestion to point me in the right direction.
