The Texas Instruments TLC5916IN is a member of the PMIC - LED Drivers family. It is designed for driving up to 16 outputs for individually adjustable current sinks with programmable flash pulse and dimming frequency.

The TLC5916IN is an ideal solution for driving LEDs in end products such as laptops, LCD screens and backlights, digital cameras, projectors, game consoles, outdoor displays, industrial and automotive applications. It is an integrated circuit (IC), which integrates control, protection, and current sink control functions into a single package. It also supports independent control of each output, allowing for different current levels and dimming settings for each LED.

The main application field for the TLC5916IN are LED lighting related solutions such as LED driver boards and LED displays. It can be used in a variety of applications such as smart lighting, architectural lighting, medical lighting, automotive lighting, and general illumination. The LED drivers that use this IC can be used to drive high-brightness LED elements with the help of the optimized current sink and dimming control functions that are present in the TLC5916IN.

The TLC5916IN features an extended voltage range of 3.2V to 16V and a wide operating temperature range of -40°C to +125°C, ensuring that it can be used in a wide range of applications. It also supports programmable levels of LED dimming and flashing and provides superior LED protection, reducing the need for expensive protection circuitry.

The TLC5916IN features an internal battery switch for inductive loads as well as a PWM dimming/flashing control. The PWM dimming/flashing control can be used to dim individual LEDs or can be used to create smooth transitions between different light intensities or flash patterns. The chip also features built-in thermal and short-circuit protection, providing added safety for the user and protecting the LEDs from damage.

The working principle behind the TLC5916IN is quite simple. It utilizes a 4-bit shift register to control up to 16 outputs, which can be individually adjusted for current sinks with programmable flash pulse and dimming frequency. The output current sink is tuned to the optimal level via the internal adjustment registers, allowing the LEDs to be dimmed or flashed using pulse-width modulation. The internal switch protects the inductive load from voltage spikes, while the internal thermal and short-circuit protection prevents damage to the LEDs.

The TLC5916IN provides an ideal solution for driving LEDs in a wide variety of applications. It supports an extended voltage range and wide operating temperature range, while the internal protection mechanisms protect the LEDs from damage. The programmable output current sink and pulse-width modulation allow for individual control of each LED and smooth transitions between different light intensities or flash patterns. All in all, the TLC5916IN is an ideal choice for LED lighting solutions.
