NIS5x2xGEVB
NIS5x2x Evaluation
Board User’s Manual
eFuse test board with multiple
subcircuits for evaluation of
overvoltage protection,
overcurrent protection,
controlled slew rate, and
thermal shutdown features
Introduction
eFuses serve a variety of purposes for electrical
system designers. They may be found connected to
3.3, 5, 12, and 24 V power rails and have many
interesting features.
The primary features of eFuses are:
Current limiting (adjustable on a few
models)
Overvoltage clamping (except on NIV6124)
Undervoltage lockout
Enable/Fault control
Thermal shutdown
Controlled slew rate
Reverse current protection on some devices
such as NIS6xxx

EVAL BOARD USER’S MANUAL
This evaluation board has many features which make
it simple to observe the functionality and
performance of the new 12 V NIS5x2x line of
eFuses. This manual documents the use of this board
with the NIS5020 latching eFuse. The properties of
the NIS5x2x evaluation board include:
Multiple connectors available for all eFuse
pins (VCC, GND, SRC, enable, ILIM,
dv/dt)
Input and output capacitors
A pushbutton switch and a MOSFET
connect the enable pin to GND or float it as
needed
Green and yellow LEDs to indicate whether
the eFuse enable pin voltage is high (device
enabled) or low (device disabled)
Five current limit resistor options available
directly on the board (20, 25, 30, 35, 40 Ω)
A jumper option to short circuit the load.
Output and GND pads are also provided for
the same purpose.
Kelvin or direct sensing options via the
jumper between pins 6 and 7
4x 200 Ω load option on the output
