Description
The STEVAL-IFP028V1 is an evaluation board
designed to analyze all IPS160H functionality.
It is designed to meet application requirements in
terms of galvanic isolation between the user
interface and the power interface. This
requirement is satisfied via optical isolation
implemented through two optocouplers, OPTO1
and OPT2, for forward signals to the device and
for diagnostic feedback signals, respectively, in
compliance with IEC 61000-4-2, IEC61000-4-4,
IEC 61000-4-5 requirements. These
requirements are satisfied by IPS160H itself and
by the U1 component (the external TVS between
V
CC
supply rail and power ground).
A dedicated GUI interface was developed to
facilitate the testing of IPS160H functionality. To
use the GUI, connect the STEVAL-IFP028V1 to
the STEVAL-PCC009V2 with a 30-way flat cable,
followed by a USB connection between the
STEVAL-PCC009V2 and the PC where the GUI
runs.
The GUI can be used to drive the STEVAL-
IFP028V1 and monitor the status of the output on
the power side, receiving fault information
available on the IPS160H DIAG pin.
The STEVAL-IFP028V1 can be operate in an 8 to
60 V range, bearing in mind that the red LED
functionality on the DIAG pin is only guaranteed
from V
CC
= 12 V and that for a supply voltage
higher than 40 V, J1 must be open to avoid
permanent damage to U1.
Finally, the STEVAL-IFP028V1 optimizes thermal
performance through a careful layout which
includes a dedicated copper area connected to
the exposed pad of the PSSO12 package, also
acting as a heatsink.
