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.

For hot-plug-in boards, the device provides in-rush
current control and programmable output ramp rate.
SGM2523 integrates over-current and short-circuit
protection. The precision over-current limit helps to
minimize over design of the input power supply, while
the fast response short-circuit protection immediately
isolates the load from input when a short-circuit case is
detected. The device allows the user to program the
over-current limit threshold between 0.1A and 1.2A via
an external resistor. Its threshold accuracy of 3%
ensures tight supervision of bus, eliminating the need
for a separate supply voltage supervisor chip.
SGM2523 is designed to protect systems such as white
goods, STBs, DTVs, smart meters and gas analyzers.

SGM2523 is a smart eFuse with enhanced built-in

The EN/nFAULT pin controls the on/off state of the

E
Toggling the EN/nFAULT pin below VENF_RST resets the
SGM2523B that has latched-off due to a fault condition.
The internal de-glitch delay on EN/nFAULT falling edge
is kept low for quick detection of power failure. For
applications where a higher de-glitch delay on
EN/nFAULT is desired, or when the supply is
particularly noisy, it is recommended to use an external
filter capacitor from the EN/nFAULT terminal to GND.
The under-voltage lockout threshold can be
programmed by using an external resistor divider from
the supply IN terminal to the EN/nFAULT terminal to
GND as shown in Figure 3. When an under-voltage or
input power fail event is detected, the internal FET is
quickly turned off. If the under-voltage lockout function

Hot-Plug-In and In-Rush Current Control
SGM2523 is designed to control the in-rush current
upon insertion of a card into a live backplane or other
"hot" power source. This limits the voltage sag on the
backplane’s supply voltage and prevents unintended
resets of the system power. A slew rate controlled
start-up (SS) also helps to eliminate conductive and
radiated interference. An external capacitor from the
SS pin to GND defines the slew rate of the output
voltage at power-on (as shown in Figure 4). The
equation governing slew rate at start-up is shown in
Equation 1:

DETAILED DESCRIPTION (continued)
Over-Load Protection
For over-load conditions, the internal current limit
amplifier regulates the output current to ILIMIT. The
output voltage droops during current limit regulation,
resulting in increased power dissipation in the device.
SGM2523 allows ILIM pin floating operation. If ILIM pin
is floating, the current limit will be set as fixed 0.2A
internally.

The total ramp time (tSS) of VOUT for 0 to VIN can be

Short-Circuit Protection
During a transient short-circuit event, the current
through the device increases very rapidly. As current
limit amplifier cannot respond quickly to this event due
to its limited bandwidth, the device incorporates a
fast-trip comparator, with a threshold IFAST-TRIP. When
the current through the internal FET exceeds IFAST-TRIP
(IOUT > IFAST-TRIP), this comparator shuts down the pass
device within 0.3μs and terminates the rapid
short-circuit peak current. The IFAST-TRIP threshold is
dependent on programmed over-load current limit and
function of RILIM. See Equation 6 for the calculation.

The SS pin can be left floating to obtain a
predetermined slew rate (tSS) on the output. When
terminal is left floating, the device sets an internal ramp
rate of ~50V/ms for output (VOUT) ramp.
For systems where load is present during start-up, the
current never exceeds the over-current limit set by RILIM
resistor for the application.

At all times load current is monitored by sensing

where:
IFAST-TRIP is fast-trip current limit in Ampere.
The fast-trip circuit holds the internal FET off for only a
few microseconds, after which the device attempts to
turn back on normally, allowing the current limit loop to
regulate the output current to ILIMIT. Then, device
behaves similar to over-load condition.
SGM2523 incorporates two distinct over-current
protection levels: the current limit (ILIMIT) and the
fast-trip threshold (IFAST-TRIP). The fast-trip and current
limit operations are shown in Figure 5.
Bias current on ILIM pin directly controls current limiting
behavior of the device, and PCB routing of this node
must be kept away from any noisy (switching) signals.

SYSTEM EXAMPLES
Protection and Current Limiting for
Primary-Side Regulated Power Supplies
Many of the above applications require precision output
current limiting and secondary side protection, driving
the need for current sensing in the secondary side. This
needs additional circuit implementation using precision
operational amplifiers. This increases the complexity of
the solution and also results in sensing losses The
SGM2523 with their integrated low-ohmic N-channel
FET provides a simple and efficient solution. Figure 7
shows the typical implementation using SGM2523.
Primary-side regulated power supplies and adapters
are dominant today in many of the applications such as
smart-phones, portable hand-held devices, white goods,
set-top-box and gaming consoles. These supplies
provide efficient, low cost and low component count
solutions for power needs ranging from 5W to 30W. But,
these come with drawbacks of:
During short-circuit conditions, the internal fast
comparator of SGM2523 turns off the internal FET in
less than 0.3μs (TYP) as soon as current exceeds
IFAST-TRIP, set by the current limit RILIM resistor.

Safety Applications
Intrinsic Safety (IS) is becoming prominent need for
safe operation of electrical and electronic equipment in
hazardous areas. Intrinsic Safety requires that
equipment is designed such that the total amount of
energy available in the apparatus is simply not enough
to ignite an explosive atmosphere. The energy can be
electrical, in the form of a spark, or thermal, in the form
of a hot surface.
current limits are not exceeded for wide operating
temperature range and variable environmental
conditions. Applications such as gas analyzers,
medical equipment (such as electrocardiographs),
portal industrial equipment, cabled power distribution
systems and hand-held motor operated tools need to
meet these critical safety standards.
The SGM2523 device can be used as simple protection
