Features
General Description
The G547 is an integrated power switch for
self-powered and bus-powered Universal Serial Bus
(USB) applications. G547E, G547F, G547G,G547H
ꢀ
90mΩ High-Side MOSFET
(G547E,G547F,G547G,G547H, G547M)
Available with 5 Versions of Current Limits with
Foldback
ꢀ
and G547M are 90mΩ RDS(ON)
.
ꢀ
ꢀ
ꢀ
ꢀ
ꢀ
ꢀ
Operating Range:2.7V to 5.5V
1mS Typical Rise Time
Fast Overcurrent Response -3ꢀs (TYPICAL)
Under voltage Lockout
100ꢀA Quiescent Supply Current
1ꢀA Maximum Shutdown Supply Current
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. A
built-in charge pump is used to drive the N-channel
MOSFET that is free of parasitic body diode to elimi-
nate any reversed current flow across the switch when
it is powered off.
ꢀ Logic Level Enable Pin, Available with
Active-High or Active-Low Version
No Reverse Current when Power Off
ꢀ
ꢀ Deglitched Open-Drain Over-Current Flag
OC is open-drain output report over-current or
over-temperature event and has typical 9ms deglitch
timeout period.

Note: Recommend connecting the Thermal Pad
to the GND for excellent power dissipation.
*Pin#6 should be considered as OUT when circuit design and PCB layout, but it is NC pin actually.

OC Function
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.
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.
Thermal Shutdown
Applications Information
Thermal shutdown protects G547 from excessive
power dissipation. If the die temperature exceeds
135°C, the MOSFETS switch is shut off. 20°C of hys-
tersis prevents the switch from turning on until the die
temperature drops to 115°C. Thermal shutdown circuit
functions only when the switch is enabled.
Supply Filtering
A 1ꢀF bypass capacitor from IN to GND, located
near the G547, 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.
Undervoltage Lockout
UVLO (undervoltage lockout) prevents the output
MOSFET from turning on until IN (input voltage) ex-
ceeds 2.5V typically. After the switch turns on, if the
voltage drops below 2.3V typically, UVLO shuts off the
output MOSFET.
Input transients must not exceed the absolute maxi-
mum supply voltage (VIN max = 6V) even for a short
duration.
EN, the Enable Input
EN must be driven logic high or logic low for a clearly
defined input. Floating the input may cause unpre-
dictable operation. EN should not be allowed to go
negative with respect to GND.
Current Limiting
The typical current limit value of G547 is 3.7A, 2.5A, 2A,
1.5A, 1A . There is foldback of current limit when VOUT
1.5V (See Typical Performance Characteristics).
