Product details

Description

This 7-bit LED dimmer for the two-line bidirectional bus (I2C) is designed to control (or dim) LEDs through the I2C interface.

Without this device, the microcontroller must be actively involved in turning on and off the LEDs (per the required dimming rate), which uses valuable processor time.

Features

1 Seven LED Driver Outputs: ON, OFF, Blinking, Fading at Programmable Rates.
Open-Drain Outputs Directly Drive LEDs to 40-mA Maximum.
Two Independent Banks of LED Drivers.
Widely Programmable Blink Rates, Fade-ON and Fade-OFF Rates and Maximum Intensity.
Outputs Not Used as LED Drivers Can Be Used as Regular General-Purpose Open-Drain Outputs.
16 Steps of Maximum Intensity Control from Fully-OFF to Fully-ON States.
Smooth Perceived T.
