Overview

This document concern the main features of PTB801DC valve drivers for ABS board with
2 x L9349 devices.
1.1

Introduction

The PTB801DC is a complete demonstrator of an ABS system based on
STMicroelectronics devices. The board implements a flexible and open design
demonstrating the capability of the STMicroelectronics 16/32 bit microcontrollers and
devices for ABS applications. The PTB801DC mounts two L9349 devices and accept
external signal coming from PTB801 MB.
