NCV7450 System Basis
Chip Evaluation Board
User's Manual

Introduction

This document describes the evaluation board for the
ON Semiconductor system basis chip (SBC) NCV7450, which
contains a CAN−FD transceiver, 5 V / 250 mA LDO regulator and HS
driver. The board provides basic connections for a device evaluation.

Evaluation Board Features

• One−row pin header providing access to all the device pins, enables

easy insertion of the evaluation board into a more complex
application setup

• Separated supply path for VS1 and VS2

• Standard CAN termination

• Position for optional ESD protection

• LED for RSTN signal activity indication

• Jumpers for enable signals
