2.8.2. Reference Schematics
The following notes apply to Figure 29 below.
J6 incorporate an USB Type A receptacle. J58 has two of them and in addition, includes an RJ-
45 (Foxconn UB11123-J51, Pulse JW0A1P0R-E).
The reference design uses an over-current detection and protection device. Two examples are
the Texas Instruments TPS2042AD and the Micrel MIC2026 dual channel power distribution
switch. The second example includes a discrete implementation.
