High-Side Power Distribution Switch
Features
General Description
120mΩ High-Side MOSFET
The G5240 is an integrated 120mΩ power switch for
4 Versions of Current Limits with Foldback
Operating Range:2.7V to 5.5V
150µS Typical Rise Time
Under voltage Lockout
65µA Quiescent Supply Current
1µA Maximum Standby Supply Current
Logic Level Enable Pin, Available with Ac-
tive-High or Active-Low Version
No Reverse Current when Power Off
SOT-23-5 Package with 2 Pin Out Options
UL Approved_#E232223
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.
Nemko IEC 60950-1 CB/CCA_scheme certifica-
tion Report #67291
Its low quiescent supply current and small package
(SOT-23-5) is particularly suitable in battery-powered
equipment, like PDA, mobile phone.
