LM66100: LM66100 design questions

Hi Team,

Here’re some information about LM66100 application.

Circuit operation principles:

1.       The circuit will include 2 independent power sources: external USB Bus and external power supply.

2.       There are 3 possible configuration for power connection:

a)      From USB Bus only

b)      From external power supply only

c)       From both USB Bus and external power supply

3.       For both of 3 configurations the following protection types are required:

a)      Reverse current protection for USB Bus

b)      Reverse voltage (and maybe also current) protection for external power supply

4.       My idea is to use 2 of LM66100 for each power source and connect between them for current sharing in case of both sources are connected

Please advise how 2 LM66100 should be connected upon the requirements listed above.

Thanks,

Shlomi
