Introduction
This application note describes the STEVAL-IFP001V1 hardware implementation. It focus
on PCB design which is critical for EMC immunity robustness and thermal management.
The VN808CM-E is a monolithic device designed in STMicroelectronics VIPower M0-3
technology. The product is intended for driving any kind of load with one side connected to
ground. It can be driven by using a 5.0V or 3.3V logic supply. This allows realizing an output
stage without optical decoupling or another level-shifting. Active current limitation, combined
with thermal shutdown and automatic restart, protect the device against accidental or long-
time short circuit and overload.
The complete solution is implemented on a double-face board with only two copper layers
which is cost-effective, also precision of routing is cost-optimized.
STEVAL-IFP001V1 is delivered in a set with CD-ROM including board fabrication data
(Gerber files), this user manual and related devices documentation (for latest information,
