The G5250 is an integrated 85mΩ 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.
G5250E/F/G/H, G5250I/J/K/L and G5250M/N/P has
open- drain
over-temperature event and has typical 9ms deglitch
timeout period.

Functional Description
Input and Output
IN (input) is the power supply connection to the logic
circuitry and the drain of the output MOSFET. OUT
(output) is the source of the output MOSFET. In a
typical application, current flows through the switch
from IN to OUT toward the load. Both OUT pins must
be connected together to the load.
Thermal Shutdown
Thermal shutdown protects G5250 from excessive
power dissipation. If the die temperature exceeds
135°C, the MOSFETS switch is shut off. 20°C of hystersis prevents the switch from turning on until the die
temperature drops to 115°C. Thermal shutdown circuit
functions only when the switch is enabled.
Undervoltage Lockout
UVLO (undervoltage lockout) prevents the output
MOSFET from turning on until IN (input voltage) exceeds 2.5V typically. After the switch turns on, if the
voltage drops below 2.3V typically, UVLO shuts off the
output MOSFET.
Current Limiting
The typical current limit value of G5250 is 2.5A, 2A,
1.5A, 1A for G5250A(E)(I) / G5250B(F)(J)/P / G5250C
(G)(K)(N) / G5250D(H)(L)(M) respectively. There is
foldback of current limit when V

OUT
OC
Function (G5250E/F/G/H, G5250I/J/K/L and
G5250M/N/P)
The
OC
open-drain output is asserted (active low)
when an over current or overtemperature shutdown
condition is encountered after a 9-ms deglitch timeout.
The output remains asserted until the overcurrent or
overtemperature condition is removed.
Applications Information
Supply Filtering
A 1µF bypass capacitor from IN to GND, located
near the G5250, is strongly recommended to control
supply transients. Without a bypass capacitor, an
output short may cause sufficient ringing on the input
(from supply lead inductance) to damage internal
control circuitry.
Input transients must not exceed the absolute maximum supply voltage (V
duration.
EN, the Enable Input
EN must be driven logic high or logic low for a clearly
defined input. Floating the input may cause unpredictable operation. EN should not be allowed to go
negative with respect to GND.
