I am reading the TI POE IC(TPS23730's datasheet), and I have some questions I would like to ask you, if you can help me I will very much appreciate it.
1.) What's the internal hot-swap MOSFET, I have no idea what's this use for? 2.) What's Oring? 3.) What's APD function and PPD function. 4.) Why need to use RTN pin, GND pin, and RTN pin, all three are ground why cannot just use one. 5.) What's beat frequency
I have read this datasheet but I still cannot understand the above question, hope someone can give some help.
