GENERAL DESCRIPTION
The SGM2566C is an ultra-low on-resistance, integrated
N-MOSFET, single-channel load switch. The device can
operate over a wide input voltage range of 0.6V to 5.7V.
It can support a 5A maximum continuous load current
and is controlled by a switch enable input (ON) pin. The
V
OUT
rise time can be programmed by setting an
additional capacitor to the SS pin.
The SGM2566C has a thermal shutdown function. When
the junction temperature exceeds +165
℃, the inner
N-MOSFET will be turned off through the thermal
shutdown circuitry, and will remain off until the die
temperature drops below +140℃. The device also has
quick output discharge function when the switch is
disabled.
The SGM2566C is available in a Green TDFN-2×2-8AL
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
circuit
design, or specifications
without prior notice.
