SGM40659/SGM40660/SGM40661
Adjustable Over-Voltage Protection Switches
GENERAL DESCRIPTION
The SGM40659/60/61 over-voltage protection devices
feature a low 27mΩ (TYP) on-resistance high current
integrated MOSFET which actively protect low-voltage
systems against voltage supply faults up to +28VDC.
An input voltage exceeding the over-voltage threshold
will cause the internal MOSFET to turn off, preventing
excessive voltage from damaging downstream devices.
When the OVLO input is connected to GND, the
SGM40659/60/61 automatically choose the internal
fixed OVLO threshold, preset to be typical 15.61V/
6.80V/5.94V (SGM40659/60/61). The over-voltage
protection threshold can be adjusted with optional
external resistors to any voltage between 4V and 20V.
In case the device temperature exceeds the maximum
junction temperature, the device switches off.
The SGM40659/60/61 are available in Green WLCSP-
1.30×0.94-6B package, and operate over an ambient
temperature range of -40to +85.

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 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.
DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuit design, or specifications without prior notice.
