(G5250 E/F/G/H) (G5250 I/J/K/L) SOT-23-5 Package UL Approved_#E232223 Nemko IEC 60950-1 CB/CCA_scheme certifica-
tion Report #67291 CSA Approved #230321
General Description
The G5250 is an integrated 85mΩ power switch for self-powered and bus-powered Universal Serial Bus (USB) applications.
Several Protection features include current limiting with foldback, and thermal shutdown to prevent catastrophic switch failure caused by increasing power dissipation when continuous heavy loads or short circuit occurs. And a built-in charge pump is used to drive the N-channel MOSFET that is free of parasitic body diode to eliminate any reversed current flow across the switch when it is powered off.
G5250E/F/G/H and G5250I/J/K/L has open-drain
OC output reports over-current or over-temperature event and has typical 9ms deglitch timeout period.
