Overview

This reference design showcases an Infrared LED illumination sub-system for Internet Protocol (IP) network cameras with day and night vision. The system features a cut filter control, LED dimming, ambient light measuring and ballasting for current of each IR LED string. Ballasting is an alternative for driving multi-string LED arrays with a single string LED driver while maintaining uniform illumination under low-light conditions. The OPT3001 Ambient Light Sensor (ALS) with precise visible light measuring and good IR rejection, is an ideal preferred replacement for photodiodes, photoresistors or other ambient light sensors.

Features

Incorporates current ballasting to equalize IR LED currents between strings in a multi-string LED array while using a single-string LED controller
Offers firmware-adjustable ambient light level thresholds and ambient light measurement modes
Offers PWM-adjustable illumination brightness levels
Offers ICR open or close control for day and night vision by using a simple motor driver
Incorporates the ability to operate from either a 12-V or 5-V power supply
Designed with headers compatible with BoosterPack™ plug-in module ecosystem with software designed to work with MSP430FR2311 MCU LaunchPad™
