Product Overview
The TLC59116 is a Texas Instruments 16-channel I2C LED sink driver for LED control applications requiring multiple constant-current sink outputs. Its OUT0 to OUT15 channels support 5 mA to 120 mA per output, with a recommended maximum output-pin voltage of 17 V. The device operates from a 3 V to 5.5 V VCC range and supports 3.3 V or 5 V nominal supply rails.
Brightness control is provided through 8-bit individual PWM with 256 steps at a fixed 97 kHz frequency and a 0% to 99.6% duty-cycle range. Group control also uses 8-bit, 256-step resolution, with 190 Hz group dimming and programmable blinking from 24 Hz to a 10.73 s period.
The I2C interface is Fast-mode Plus compatible, with timing support for Standard-mode, Fast-mode, and Fast-mode Plus clock ranges up to 1000 kHz. SCL, SDA, RESET, and address inputs A0 to A3 are 5.5 V tolerant. Package options include a 28-pin TSSOP (PW) and 32-pin VQFN (RHB), supporting compact LED driver assembly layouts.
