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 catas-

trophic switch failure caused by increasing power dis-

sipation 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.

Output ( OC )

Available for 3 Kinds of Pin Out (G5250 E/F/G/H)

(G5250 I/J/K/L) (G5250M/N/P)

SOT-23-5 and TSOT-23-5 Package

UL Approved_#E232223

Nemko IEC 60950-1 CB/CCA_scheme certifica-

tion Report #67291

CSA Approved #230321

G5250E/F/G/H, G5250I/J/K/L and G5250M/N/P has

open- drain OC output reports over-current or

over-temperature event and has typical 9ms deglitch

timeout period.
