Applications
High-Side Power Protection Switch USB Power Management USB Host and Self-Powered Bubs USB Bus-Powered Hubs Hot Plug-In Power Supplies Battery-Charger Circuits General Description The G5243A is an integrated 120m Ω 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. G5243A has shutdown discharge function when power switch is off. The typi- cal pull low resistor is 75Ω. Its low quiescent supply current and small package (SOT-23-5) is particularly suitable in battery-powered equipment, like PDA, mobile phone.
