5 Description (continued)
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 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%. 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-Q1 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 TLC59116-Q1 device outputs.
Software programmable LED Group and three Sub Call I²C-Bus addresses allow all or defined groups of
TLC59116-Q1 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 TLC59116-Q1 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.
