SGM2578
Ultra Small, Low Input Voltage,
Low RON Load Switch
GENERAL DESCRIPTION
FEATURES
The SGM2578 is a single channel power distribution
switch. The switch operates from a wide range of 1V to
5V supply voltage, and is controlled by the EN pin. It
can be used in USB power distribution applications.
● Low Input Voltage: 1V to 5V
● Low On-Resistance (RON
)

R
ON = 54mΩ at VIN = 5.0V
ON = 54mΩ at VIN = 3.6V
ON = 58mΩ at VIN = 2.5V
ON = 74mΩ at VIN = 1.8V
ON = 84mΩ at VIN = 1.2V
ON = 84mΩ at VIN = 1.0V
A 54mΩ low RON N-MOSFET is integrated. The small
size and quiescent current make the device very suitable
for space limited, battery-powered applications.
A number of protection features are provided in the
device including soft-start, current limit and thermal
shutdown. The internal reverse-voltage function will
protect devices on the input side of the switch. The
SGM2578 has automatic discharge function to quickly
discharge VOUT in the disabled status.
● Continuous Switch Current: 1A (MAX)
● Quiescent Current: 5μA (TYP)
● Shutdown Current: < 1.5μA
● Quick Output Discharge (QOD)
● Soft-Start Function
● Evaluated to IEC 60950-1, Ed 2, Am1, Annex CC,
Test Program 1 with CB Report
The SGM2578 is available in a Green WLCSP-0.9×0.9-4B
package and operates over a temperature range of
-40℃ to +85℃.
● Available in a Green WLCSP-0.9×0.9-4B 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.
