Part Number : G5258
Function : Dual Power Distribution Switch
Package : SOP 8, TDFN3X3-8 Pin Type
Manufacturers : Global Mixed-mode Technology Inc. ( http://www.gmt.com.tw )
The G5258 is an integrated dual channel 87mΩ 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.
