ST EVAL-L99MOD5xXP User manual

Introduction

This document describes the STSW-L99MOD5xXP graphical user interface (GUI) dedicated to set and control the EVAL-

L99MOD5xXP family evaluation kit.

The EVAL-L99MOD5xXP evaluation kit consists in a motherboard and a daughterboard on which the L99MOD5xXP device is

assembled. Both of these evaluation boards provide electronic control modules with enhanced power management

functionalities including a standby mode. These evaluation boards are designed to drive multiple brushed DC motors and

additional loads in high-side configuration, such as bulbs, LEDs or protected supply.

The STSW-L99MOD5xXP has been developed using C++ and works with a motherboard based on an SPC560B microcontroller

which is programmed with a dedicated firmware to drive the specific L99MOD5xXP device assembled on the daughterboard.
