The TLC59108IPWR from Texas Instruments is a highly efficient 8-bit Fast-mode Plus (Fm+) I2C-bus LED driver with an integrated mode-selectable, constant-current output driver. This versatile IC is designed to produce a consistent and precise current for each output, which can be used to drive LEDs with a high level of brightness control.

Key Features

• I2C Interface: The device supports Fast-mode Plus I2C-bus (Fm+) with up to 30 mA output drive capability on SDA and up to 10 MHz clock frequency.
• Output Current: Each of the eight LED outputs can be off, on (no PWM control), set at its individual PWM controller value or at both individual and group PWM controller values.
• Constant Current Output: The output current from each output can be programmed from 5.5 mA to 120 mA, allowing for a wide range of LED brightness control.
• Hardware Dimming: Grouped dimming/blinking can be controlled using hardware pins without the need for an I2C interface, providing additional flexibility for simple use cases.
• Thermal Shutdown Protection: The TLC59108IPWR includes an integrated thermal shutdown protection feature to safeguard the device and connected components from overheating.
• Power-Supply Voltage: The device operates from a 3.0 V to 5.5 V supply, making it suitable for various applications.

Applications

The TLC59108IPWR is ideal for a variety of LED driving applications, including:

• LED display backlighting
