5 Description (continued)

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 TLC59208F 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 TLC59208F device outputs.

Software programmable LED Group and three Sub Call I2C bus addresses allow all or defined groups of TLC59208F 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.

Three hardware address pins allow up to 64 devices on the same bus.

The software reset (SWRST) Call allows the master to perform a reset of the TLC59208F 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.
