TLC59116F中文资料16 位快速模式增强版 (FM+) I2C 总线 LED 驱动器数据手册TI规格书

描述 Description

The TLC59116F is an I2C-bus controlled 16-channel LED driver optimized for red/green/blue/amber (RGBA) color mixing applications. 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% to allow the 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% that is used to either dim or blink all LEDs with the same value.

特性 Features

• 16 LED Drivers (Each Output Programmable at OFF, ON, LED Brightness, and Group Dimming/Blinking Mixed With Individual LED Brightness)
• 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 Blinking With Frequency Programmable From 24 Hz to 10.73 s and Duty Cycle from 0% to 99.6%
• Four Software-Programmable I2C Bus Addresses (One LED Group Call Address and Three LED Sub-Call Addresses) Allow Groups of Devices to be AddressedSimultaneously in Any Combination (For example, One Register Used for ‘All Call’ So All the TLC59116Fs on the I2C Bus Can be Addressed at the Same Time and the Second Register Used for Three Different Addresses So That 1/3 of all Devices on the Bus Can Be Addressed at the Same Time in a Group). Software Enable and Disable for I2C Bus Address.
• Up to 14 Possible Hardware Adjustable Individual I2C Bus Addresses Per Device so That Each Device Can be Programmed
• 120-mA Maximum Output Current
• 25-MHz Internal Oscillator Requires No External Components
• Internal Power-On Reset
• No Glitch on Power Up
• Supports Hot Insertion
• 3.3-V or 5-V Supply Voltage
• 28-Pin TSSOP (PW)
• APPLICATIONS
• Small Signage
• Industrial Equipment
