TLC5948APWPR Typical application Circuitry

TLC5948APWPR

The TLC5948APWPR is a high-performance, 48-channel LED driver from Texas Instruments. It's designed to control the brightness and color of LEDs, making it particularly suitable for applications like LED displays and backlighting, signage, and decorative LED lighting.

Functional Overview of TLC5948APWPR:

- This LED driver chip contains 48 channels, each capable of providing pulse-width modulated (PWM) outputs to control the brightness of individual LEDs.

- The chip also includes six-dot correction data registers to compensate for variations in LED forward voltage, ensuring color accuracy and consistency across multiple LEDs.

- The chip operates through a grayscale control clock input and communicates via an SPI-compatible serial interface.

Application Scenarios for TLC5948APWPR: The TLC5948APWPR shines in applications like LED video displays, mobile appliances, and general LED lighting applications.

Parametric Characteristics:

- The TLC5948APWPR operates from a power supply voltage of 3V to 5.5V.

- It supports constant-current outputs ranging from 2 mA to 60 mA.

- The chip also supports 16-bit (65536 levels) of grayscale PWM control and 7-bit (128 levels) of dot correction. To illustrate, let's consider an application in LED video displays:

Power Supply and Ground Pins:

- VCC (Pin 41): This pin should be connected to a 3V to 5.5V power supply.

- GND (Pins 21, 22, 43, and 44): Join these pins to the system ground.

Serial Interface Pins: SDI (Pin 33), SCLK (Pin 34), XLAT (Pin 35), and SOUT (Pin 36): These pins should be connected to the corresponding SPI interface pins on the microcontroller.

Output Pins: OUT0 - OUT47 (Pins 1-20, 23-32, 37-40, 42): These are the LED output pins. Each pin can be connected to an LED to control its brightness.

Designing with TLC5948APWPR requires proper consideration of the following:

1. Power Supply: The VCC supply must be stable and within the specified range to prevent damage to the TLC5948APWPR.

2. Heat Management: With high LED counts, thermal management becomes a key consideration. Proper heatsinking or active cooling may be needed in some cases.

3. LED Forward Voltage: Since the TLC5948APWPR provides constant current control, the LED forward voltage must be less than the supply voltage for proper operation.

In conclusion, the TLC5948APWPR offers an excellent solution for high-resolution, complex LED displays and lighting applications. By effectively managing power supply, heat, and LED characteristics, designers can make the most out of this versatile chip.
