TLC59116IRHBR

The TLC59116IRHBR is a 16-bit fast-mode plus (FM+) I²C-bus constant-current LED Sink Driver optimized for red/green/blue/amber (RGBA) colour mixing and backlight application. Each LED output has its own 8-bit 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 8-bit resolution (256 steps) group PWM controller has both a fixed frequency of 190Hz and an adjustable frequency between 24Hz 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. 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. The TLC59116 operates with a supply voltage range of 3 to 5.5V and the outputs are 17V tolerant.

• Four hardware address pins allow 14 TLC59116 devices to be connected to same I²C bus
• Software reset feature (SWRST call) allows the device to be reset through the I²C-bus
• Open-load and over-temperature detection mode to detect individual LED errors
• Output current adjusted through an external resistor
• 25MHz Internal oscillator requires no external components
• Internal power-ON reset
• Noise filter on SCL and SDA inputs
• No glitch on power-up
• Active-low reset
• Supports hot insertion
• Low standby current consumption
• 5.5V Tolerant input
• Green product and no Sb/Br
