TLC59108 8 位 Fm+ I2C 总线恒流下沉式 LED 驱动器
TLC59108 描述
The TLC59108 is an I2C bus controlled 8-bit LED driver that is optimized for red/green/blue/amber (RGBA) color
mixing and backlight application for amusement products. Each LED output has its own 8-bit resolution
(256 steps) fixed-frequency individual PWM controller that operates at 97 kHz, with a duty cycle that is adjustable
from 0% to 99.6%. The individual PWM controller allows each LED to be set to a specific brightness value. An
additional 8-bit resolution (256 steps) group PWM controller has both a fixed frequency of 190 Hz and an
adjustable frequency between 24 Hz to once every 10.73 seconds, with a duty cycle that is adjustable from 0%
to 99.6%. The group PWM controller dims or blinks all LEDs with the same value.

TLC59108 特性
- Eight LED Drivers (Each Output Programmable
At Off, On, Programmable LED Brightness,
Programmable Group Dimming/Blinking Mixed
With Individual LED Brightness
- Eight Constant-Current Open-Drain Output
Channels
- 256-Step (8-Bit) Linear Programmable
Brightness Per LED Output Varying From Fully
Off (Default) to Maximum Brightness Using a
97-kHz PWM Signal
- 256-Step Group Brightness Control Allows
General Dimming (Using a 190-Hz PWM Signal
From Fully Off to Maximum Brightness (Default)
- 256-Step Group Blinking With Frequency
Programmable From 24 Hz to 10.73 s and Duty
Cycle From 0% to 99.6%
- Four Hardware Address Pins Allow 14 TLC59108
Devices to be Connected to the Same I2C Bus
- Four Software-Programmable I2C Bus
Addresses (One LED Group Call Address and
Three LED Sub Call Addresses) Allow Groups
of Devices to be Addressed at the Same Time
in Any Combination. For Example, One
Register Used for All Call, so That All the
TLC59108 Devices on the I2C Bus Can be
Addressed at the Same Time, and the Second
Register Can be Used for Three Different
Addresses so That One-Third of All Devices
on the Bus Can be Addressed at the Same Time
in a Group.
- Software Enable and Disable for I2C Bus
Address
- Software Reset Feature (SWRST Call) Allows
Device to be Reset Through I2C Bus
- Up to 14 Possible Hardware-Adjustable
Individual I2C Bus Addresses Per Device, So
That Each Device Can Be Programmed
- Open-Load/Overtemperature Detection Mode
to Detect Individual LED Errors
- Output State Change Programmable on the
Acknowledge or the Stop Command to Update
Outputs Byte by Byte or All at the Same Time
(Default to Change on Stop)
- Output Current Adjusted Through an External
Resistor
- Constant Output Current Range: 10 mA to 120 mA
- Maximum Output Voltage: 17 V
- 25-MHz Internal Oscillator Requires No External
Components
- 1-MHz Fast Mode Plus Compatible I2C Bus
Interface With 30-mA High Drive Capability on
SDA Output for Driving High-Capacitive Buses
- Internal Power-On Reset
- Noise Filter on SCL/SDA Inputs
- No Glitch on Power Up
