8-BIT FM+ I2C BUS LED DRIVER
FEATURES
1
Eight LED Drivers (Each Output Programmable
at OFF, ON, Programmable LED Brightness,
Programmable Group Dimming/Blinking Mixed
With Individual LED Brightness)
Eight Open-Drain Output Channels
256-Step (8-Bit) Linear Programmable
Brightness Per LED Output Varying From Fully
Off (Default) to Maximum Brightness Using a
97-kHz PWM Signal
256-Step Group Brightness Control Allows
General Dimming [Using a 190-Hz PWM Signal
From Fully Off to Maximum Brightness
(Default)]
256-Step Group Blinking With Frequency
Programmable From 24 Hz to 10.73 s and Duty
Cycle From 0% to 99.6%
Four Hardware Address Pins Allow 14
TLC59108F Devices to be Connected to the
Same I2C Bus
Four Software Programmable I2C Bus
Addresses (One LED Group Call Address and
Three LED Sub Call Addresses) Allow Groups
of Devices to be Simultaneously Addressed
Any Combination (For Example, One Register
Used for ‘All Call’ so That All the TLC59108Fs
on the I2C Bus Can be Simultaneously
Addressed and the Second Register Used for
Three Different Addresses so That One Third
of All Devices on the Bus Can be
Simultaneously Addressed)
Software Enable and Disable for I2C Bus
Address
Software Reset Feature (SWRST Call) Allows
the Device to be Reset Through the I2C Bus
Up to 14 Possible Hardware Adjustable
Individual I2C Bus Addresses Per Device so
That Each Device Can be Programmed
Output State Change Programmable on the
Acknowledge or the STOP Command to
Update Outputs Byte-by-Byte or All at the
Same Time (Default to 'Change on STOP')
