SGM2571  
5.5V, 1A, 34RON Load Switch with  
Reverse Current Protection  
GENERAL DESCRIPTION  
FEATURES  
The SGM2571 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  
R
R
ON = 34mΩ at VIN = 5V  
ON = 34mΩ at VIN = 3.3V  
The device contains a 34mΩ low RON N-MOSFET  
controlled by the ON pin. 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  
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 SGM2571 offers  
the quick output discharge function in disable status.  
Rise Time:  
SGM2571AD: 85μs (TYP)  
SGM2571BD: 1600μs (TYP)  
SGM2571CD: 2200μs (TYP)  
The SGM2571 is available in a Green WLCSP-0.8×0.8-4B  
package.

OVERSTRESS CAUTION  
ABSOLUTE MAXIMUM RATINGS  
Stresses beyond those listed in Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to  
absolute maximum rating conditions for extended periods  
may affect reliability. Functional operation of the device at any  
conditions beyond those indicated in the Recommended  
Operating Conditions section is not implied.

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.

DETAILED DESCRIPTION  
The SGM2571 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.  
Quick Output Discharge  
The quick output discharge (QOD) feature is available  
for SGM2571. If the ON pin is pulled low, a discharge  
resistor of 270Ω (TYP) is connected between VOUT  
and GND pins to prevent the output from floating when  
the switch is disabled.  
Control Pin  
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  
SGM2571 is a single channel, up to 1A 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 SGM2571 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

Reverse Current Protection  
APPLICATION INFORMATION (continued)  
Figure 5 shows how the reverse current protection circuit  
Reverse Current Protection  
is activated in SGM2571. Pulling the ON pin down, the  
device is shut down and an external voltage (VFORCE) is  
forced to VOUT pin, the reverse current is tested very  
small given by IRC_VIN. This will prevent any large extra  
current reverse from the VFORCE (added on VOUT) to VIN.  
If the ON pin is pulled low, the device is disabled, while  
VIN > 1V or VOUT > 1V is met, the reverse current  
protection function is activated. This function prevents  
the current flowing from VOUT to VIN, and is very  
useful when SGM2571 is disabled and the output  
needs to be driven by another voltage source.  
Power Supply Recommendations  
VSRC  
The SGM2571 is designed for a wide operate input  
voltage range of 1V to 5.5V. Place a 1μF input bypass  
capacitor close to the device terminal is recommended.

Due to QOD  
In many terminal devices, each module needs to be  
powered up in a pre-determined manner. SGM2571 can  
set a power sequence by the tDELAY without extra GPIO,  
and may reduce inrush current. Figure 6 shows the  
sequence that the ON pin of first load switch is tied to  
the VIN, and the second load switch ON pin is tied to  
the VOUT of first load switch. The second load switch is  
powered up when the first load switch is turned on, this  
is the fixed sequence and the delay time set by default
