GENERAL DESCRIPTION
The SGM2566A and SGM2566B are single channel
load switches that provide configurable rise time to
minimize inrush current. The load switch contains an N-
MOSFET that can operate over an input voltage range
of 0.8V to 5.3V (≤ V
BIAS
) and can support a maximum
continuous current of 6A. Each of switches is controlled
by an on and off input (EN/nFAULT), which is capable of
interfacing directly with low-voltage control signals. In
the SGM2566A, a 260Ω on-chip load resistor is added
for quick output discharge when switch is turned off.
The SGM2566A and SGM2566B are available in Green
TDFN-2×2-8L package. They are rated over the -40℃
to +105℃ temperature range.

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 by ESD if you don’t
pay attention to ESD protection. 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 very small parametric changes could cause
the device not to meet its published specifications.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit
design, or specifications
without prior notice.
