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
