Application note

Using the output detection feature of the high-brightness

LED driver STP08CDC596 evaluation board

Introduction

This document describes how to implement a complete solution for driving a high-brightness

LED array. Based on STP08CDC596 drivers and controlled by an ST7FLITE3x

microcontroller, there are two versions of the evaluation board:

Note:

The STP08CDC596 LED driver is replaced by the new, higher performing STP08DP05 LED

driver. The two available versions of the evaluation board with the STP08DP05 replace the

STEVAL-ILL002V1 and the STEVAL-ILL002V2, and are described in application note

AN2478.

The new boards available are:

Forty high-brightness LEDs are arranged on the board in a 5x8 matrix. The matrix is driven

by five 8-channel STP08CDC596 drivers.

The main features of the evaluation board are:

The innovative feature of the STP08CDC596 is the full output error detection function which

enables output status checking without invasive testing (via software only).

For more information about other boards based on the STPxxC/L596 driver family, refer to

application note AN2141 which provides details concerning the basic features of the driver

family, the microcontroller interface and chip power dissipation. Refer to user manual

UM0181 for information about how to get started using the evaluation boards.
