TIDA-00560

16-channel Status LED Driver for PLC Modules Reference Design

TIDA-00560

Design files

Overview

The objective of TIDA-00560 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 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 mA to 35 mA)
  • 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
Industrial

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
