TLC59108F 8 位快速模式+ (FM+) 12C 总线 LED 驱动器
TLC59108F 描述
The TLC59108F is an I2C bus controlled 8-bit 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.
Each LED output can be off, on (no PWM control), set at its individual PWM controller value or at both individual
and group PWM controller values. The TLC59108F operates with a supply voltage range of 3 V to 5.5 V and the
outputs are 17 V tolerant. LEDs can be directly connected to the TLC59108F device outputs.
Software programmable LED group and three sub call I2C bus addresses allow all or defined groups of
TLC59108F devices to respond to a common I2C bus address, allowing for example, all the same color LEDs to
be turned on or off at the same time or marquee chasing effect, thus minimizing I2C bus commands.
Four hardware address pins allow up to 14 devices on the same bus.
The software reset (SWRST) call allows the master to perform a reset of the TLC59108F through the I2C bus,
identical to the power-on reset (POR) that initializes the registers to their default state causing the outputs to be
set high (LED off). This allows an easy and quick way to reconfigure all device registers to the same condition.
