GENERAL DESCRIPTION
The SGM2567A is a single load switch with reverse
current protection function. The device can operate
from 2.2V to 5.5V single supply and has the ability to
drive up to 4A continuous current.
The device contains a 15mΩ low R
ON
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 (> V
IH
), the pull-down
resistor is disconnected, then the standby current is very
low and power loss can be reduced. The small package
and low R
ON
make the device very suitable for space
limited, battery powered applications.
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 SGM2567A offers
the quick output discharge function in disable status.
The SGM2567A is available in a Green WLCSP-
1.45×0.95-6B package.

OVERSTRESS CAUTION
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 SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure
to observe proper handling
and installation procedures
can cause damage. ESD damage can range from subtle
performance
degradation to
complete 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.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
