16-channel Status LED Driver for PLC Modules Reference Design

Overview

TopologyOther Topology
IC revisionE1

Description

The objective of the TIDA-00560 TI Design is to demonstrate a multi-channel LED driver as required in PLC I/O modules to indicate the status of several analog, digital input, and output channels. Important requirements for such a design like low static current, low component count, minimal PCB requirements, and an integrated LED diagnostic features are addressed with this design. The two layer single-side component mounted board is compatible with the BeagleBone cape specification for rapid evaluation with the BeagleBone platform.

Features

  • 16-channel shift register with wide range constant current sinks (2-35mA)
  • Two-level selectable LED brightness to compensate for ambient light
  • Diagnostic features: LED open and LED shorted to ground
  • Standardized SPI connects seamlessly to standard processors
  • Number of channels can be increased by daisy-chaining multiple LED driver devices
  • BeagleBone cape support for easy evaluation

Typical applications

  • Fire Alarm Control Panel (FACP)
  • HVAC System Controller
  • Remote Annunciator
  • Intrusion Control Panel
