TLC59116FIPWR集成电路（IC）的LED驱动器规格书PDF中文资料

TLC59116FIPWR属于集成电路（IC）的LED驱动器。由德州仪器制造生产的TLC59116FIPWRLED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。

1 Features

1. 16 LED Drivers (Each Output Programmable at

OFF, ON, LED Brightness, and Group

Dimming/Blinking Mixed With Individual LED

Brightness)

. 16 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

TLC59116F 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 Simultaneously 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.

. Software Reset Feature (SWRST Call) Allows the

Device to be Reset Through the I2C Bus

. Up to 14 Possible Hardware Adjustable Individual

I2C Bus Addresses Per Device so That Each

Device Can be Programmed

. 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).

. 120-mA Maximum Output Current

. 17-V Maximum Output Voltage

. 25-MHz Internal Oscillator Requires No External

Components

. 1-MHz Fast-Mode Plus (FM+) Compatible I2C Bus

Interface With 30 mA High Drive Capability on

SDA Output for Driving High Capacity Buses

. Internal Power-On Reset

. Noise Filter on SCL/SDA Inputs

. No Glitch on Power Up 1

• Active-Low Reset

• Supports Hot Insertion

• Low Standby Current

• 3.3-V or 5-V Supply Voltage

• 5.5-V Tolerant Inputs

• 28-Pin TSSOP (PW)

• –40°C to 85°C Operation

2 Applications

. Gaming

. Small Signage

. Industrial Equipment

3 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.
