SGM2574
5.5V, 1A, 34mΩ RON Load Switch with
Reverse Current Protection
GENERAL DESCRIPTION
FEATURES
The SGM2574 is a single load switch with reverse
current protection and controlled turn-on. The device
can operate from 1V to 5.5V single supply and has the
ability to drive up to 1A continuous current.
● Input Voltage Range: 1V to 5.5V
● Maximum Continuous Current: 1A
● Low On-Resistance
RON = 34mΩ at VIN = 5V
RON = 34mΩ at VIN = 3.3V
The device contains a 34mΩ low RON N-MOSFET
controlled by the ON pin. When the power supply is
turned on for the first time, a smart pull-down resistor is
used to float the ON pin until the system is stable. Once
the ON pin reaches a high voltage (> VIH), the pull-down
resistor is disconnected, then the standby current is very
low and power loss can be reduced. The small package
and low RON make the device very suitable for space
limited, battery powered applications.
● Low Shutdown Current: 90nA (TYP)
● Reverse Current Protection When Disabled
● Low Threshold 1.8V GPIO Control Input
● Bidirectional Power Supply for Power Zone
Application
● Rise Time:
SGM2574A/SGM2574AD: 60μs (TYP)
SGM2574BD: 1600μs (TYP)
● Quick Output Discharge
The device supports a wide input voltage range, which
is suitable for many different voltage rails. The rise time
is used to avoid inrush current. The SGM2574AD/
SGM2574BD offer the quick output discharge function
in disable status.
(SGM2574AD/SGM2574BD Only)
● Available in a Green WLCSP-0.8×0.8-4B Package
APPLICATIONS
The SGM2574 is available in a Green WLCSP-0.8×0.8-4B

ESD Susceptibility
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

Reverse Current Protection
DETAILED DESCRIPTION
The SGM2574 is a small, 4-ball, 1A load switch. A low
on-resistance N-MOSFET is integrated, which makes a
low voltage drop across the device. To choose suitable
rise time is always used to avoid inrush current.
connected between VOUT and GND pins to prevent the
output from floating when the switch is disabled.
Functional Modes
The connection of the VOUT pin is shown in Table 1.
Control Pin
Table 2 shows the smart-ON functions.
The ON pin can control the device. Pulling the ON pin
high enables the device. Logic high of VIH on the ON
pin will enable the device and VIL will turn off it. It has
the ability to interface with low-voltage GPIO. It can
support with 1.8V, 2.5V, 3.3V GPIOs.

APPLICATION INFORMATION
SGM2574 is a single channel, up to 2A current capability
load switch with low on-resistance. The device has a
wide input range, which can be used in different end
equipment to set power sequence, reduce inrush
current and maintain low standby leakage current. The
typical application circuit of SGM2574 is shown in
Figure 4.
Input Capacitor
A 1μF input capacitor (CIN) is recommended to use
between VIN and GND close to the device pins. It can
limit the voltage drop on the input supply. Larger CIN
can reduce voltage dip in high current applications.
Output Capacitor
A 0.1μF output capacitor (COUT) should be placed
between VOUT and GND close to the device pins. This
capacitor will prevent parasitic board inductances from
forcing VOUT below GND when the switch is turned off.
To improve the VIN dropping when the device is turned
on, it is recommended that CIN is placed greater than

circuit is activated in SGM2574. Pulling the ON pin

large extra current reverse from the VFORCE (added on
If the ON pin is pulled low, the device is disabled, while
VIN > 1V or VOUT > 1V is met, the reverse current

the current flowing from VOUT to VIN, and is very
useful when SGM2574 is disabled and the output
needs to be driven by another voltage source.
