G5243A
High-Side Power Distribution Switch
Features
General Description
120mΩ High-Side MOSFET
The G5243A is an integrated 120mΩ power switch for
2A of Current Limits with Foldback
Operating Range:2.7V to 5.5V
1.9ms Typical VOUT Turn-On Rise Time
Under voltage Lockout
65µA Quiescent Supply Current
1µA Maximum Standby Supply Current
Active-High Enable Pin
No Reverse Current when Power Off
Shutdown Discharge Function at OUT Pin
SOT-23-5 Package
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.
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
Its low quiescent supply current and small package
(SOT-23-5) is particularly suitable in battery-powered
equipment, like PDA, mobile phone.
