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%
• 64 Programmable Slave Addresses Using
Three Hardware Address Pins
• 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 TLC59208Fs
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
• Up to 64 Possible Hardware Adjustable
Individual I²C Bus Addresses Per Device so
That Each Device Can be Programmed
Individually
• 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')
• Maximum Output Current: 50 mA
• Maximum Output Voltage: 17 V
• 25-MHz Internal Oscillator Requires no
External Components
• 1-MHz Fast-Mode Plus (FM+) Compatible I²C
Bus Interface With 30 mA High Drive
Capability on SDA Output for Driving High
Capacitive Buses
