TLC59116IPWR .

产品概述

The TLC59116IPWR is a 16bit fast mode plus (FM+) I2C bus constant current LED sink driver in 28 pin TSSOP package. It is optimized for red/green/blue/amber (RGBA) colour mixing and backlight application. Each LED output has its own 8bit resolution (256 steps) fixed frequency individual PWM controller that operates at 97KHz 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 8bit resolution (256 steps) group PWM controller has both fixed frequency of 190Hz and adjustable frequency between 24Hz to once every 10.73seconds with a duty cycle that is adjustable from 0% to 99.6%. The group PWM controller dims or blinks all LEDs with same value. Each LED output can be off, on (no PWM control) or set at its individual PWM controller value at both individual and group PWM controller values.

• Constant output current range from 5mA to 120mA
• Maximum output voltage of 17V
• 16 constant current output channels
• 3.3V or 5V supply voltage
• Four hardware address pins allow 14 TLC59116 devices to be connected to same I2C bus
• 1MHz fast mode plus (FMT) compatible I2C bus interface with 30mA high drive capability
• Internal power on reset, no glitch on power up
• Noise filter on SCL and SDA inputs
• Open load and overtemperature detection mode to detect individual LED errors
• Operating temperature range -40°C to 85°C
