SGM2529
5A, 5V Electronic Fuse (eFuse)
with Thermal Shutdown
GENERAL DESCRIPTION
FEATURES
The SGM2529 is a compact electronic fuse (eFuse)
with a complete set of protection functions. The
SGM2529 provides excellent accuracy, making it very
suitable for many system protection applications.
● 5V Electronic Fuse with Surge up to 30V
● Extremely Low RDS(ON) for the Integrated
Protection Switch: 26mΩ (TYP)
● 3-State ENABLE/FAULT Pin, Bidirectional Interface
● Programmable Soft-Start Time
It provides accurate over-voltage (OV) and under-
voltage lockout (UVLO) protections, which ensure tight
supervision of bus voltages and eliminate the need for
supervisor circuits. The over-voltage (OV) protection
will clamp the eFuse output at a fixed level during input
voltage surges. During the input voltage transient, the
internal FET remains on, which allows 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.
● Programmable Current Limit up to 5A
● Thermal Shutdown Options:
SGM2529A: Thermal Latch-Off with VCLAMP
SGM2529B: Thermal Auto-Retry with VCLAMP
SGM2529C: Thermal Latch-Off without VCLAMP
● Fault Output for Thermal Shutdown
● Accurate Under-Voltage Lockout
● Accurate Over-Voltage Clamp (SGM2529A and
SGM2529B)
● Available in a Green TDFN-3×3-10L Package
The SGM2529 is available in a Green TDFN-3×3-10L
package.

OVERSTRESS CAUTION
ABSOLUTE MAXIMUM RATINGS
Operating Input Voltage Range (VCC to GND) (1)
Stresses beyond those listed in Absolute Maximum Ratings

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 Susceptibility
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.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete 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.
HBM.............................................................................2000V
CDM ............................................................................1000V
NOTE: 1. Negative voltage will not damage device provided
that the power dissipation is limited to the rated allowable
power for the package.

1
GND
Ground.
Internal dV/dt Circuit. Leaving this pin open will allow the device to ramp up in 1.4ms. An
external capacitor between this pin and GND will set the slew rate according to the
application requirements.
Enable or Fault Pin. This pin is a 3-state, bidirectional interface. Asserting ENABLE/FAULT
pin high enables the device. When the thermal shutdown occurs, the device sinks current
from ENABLE/FAULT, and pulls the pin low to alert the host (this pin is used as output
port).

Current Limit Pin. This pin is used to set the overload and short-circuit current limit levels by
placing a resistor.
