SGM40657/SGM40658
High-Current Over-Voltage Protector
GENERAL DESCRIPTION
The SGM40657/8 over-voltage protection devices
feature a low 20mΩ (TYP) RON internal FET and protect
low-voltage systems against voltage faults up to +28VDC.
An internal clamp also protects the devices from surges
up to +120V. When the input voltage exceeds the
over-voltage threshold, the internal FET is turned off to
prevent damage to the protected downstream
components.
The over-voltage protection threshold can be adjusted
with optional external resistors to any voltage between
4V and 20V. If the OVLO input is below the external
OVLO select voltage, the SGM40657/8 automatically
choose the internal trip thresholds. The internal
over-voltage thresholds (VIN_OVLO) are preset to be
6.82V/5.95V typical (SGM40657/8). The devices
feature an open-drain ACOK output indicating a
stable supply between minimum supply voltage and
VOVLO. The SGM40657/8 are also protected against
over-current events by an internal thermal shutdown.
The SGM40657/8 are available in Green 12-Ball CSP
package and operate over an ambient temperature
range of -40to +85.

NOTES:
1. Non-frequent repeat peak voltage during input surge
transient and ESD transient is not subject to this rating value,
which may go higher than 35V during the surge test.
2. Surge test in compliance with IEC61000-4-5 specification.
3. Survives burst pulse up to +120V with 2Ω series resistance.
4. Continuous current limit may vary with the circuit board
thermal dissipation condition.
5. If protection discharging triggered, the discharging keeps
until the supply falls below the hysteresis range. Continuously
force driving during discharging with a voltage in the
hysteresis range would cause overstress or even damage the
device. Supply voltage within the hysteresis range is not
recommended. A 1kΩ resistor should be inserted in supply
path for clamp voltage evaluation to avoid overstress damage
by unintended triggering.
OVERSTRESS CAUTION
Stresses beyond those listed may cause permanent damage
to the device. Functional operation of the device at these or
any other conditions beyond those indicated in the operational
section of the specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, specification or other related things if necessary
without notice at any time.
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.
