The SGM2554 is an integrated 95mΩ (TYP) power switch
for self-powered and bus-powered Universal Series Bus
(USB) applications. 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. Low quiescent supply
current and small package are particularly suitable in
battery-powered portable equipment.
Several protection functions include soft-start to limit
inrush current during plug-in, current limiting at 1.85A to
meet USB power requirement, and thermal shutdown to
protect damage under over current conditions. SGM2554AYN5G/TR SGM2554BYN5G/TR
