GENERAL DESCRIPTION
The SGM2533 and SGM2534 are compact, feature rich
eFuses with a full suite of protection functions. The
precision ±15% current limit provides excellent
accuracy and makes the devices well suited for many
system protection applications.
There are two over-voltage protection options: 5V
system for SGM2533 and 12V system for SGM2534.
The over-voltage protection (OVP) will clamp the eFuse
output at a fixed level during input voltage surges.
During the input voltage transient, the internal MOSFET
remains on, allowing the load to continue to operate. If
the transient duration remains long, the accumulated
heat will cause the eFuse thermal shutdown. Once in
thermal shutdown, latch-off and auto-retry thermal
options are available.
The SGM2533 and SGM2534 are available in a Green
TDFN-3×3-10L 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.
