TLC59108F,pdf(8-BIT FM+ I2C BU

特性

• 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’)
• Maximum Output Current: 120 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
• Internal Power-On Reset
• Noise Filter on SCL/SDA Inputs
• No Glitch on Power Up
• Active-Low Reset (RESET)
• Supports Hot Insertion
