Description and Introduction

4096 Step Grayscale LED Driver w/Dot-Correction The TLC5940PWP is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Channels:** 16  
- **Output Current:** 5–120 mA per channel (adjustable via external resistor)  
- **Supply Voltage (VCC):** 3.0 V to 5.5 V  
- **Logic Voltage (VLOGIC):** 3.0 V to 5.5 V  
- **Dot Correction:** 64 steps (6-bit) per channel  
- **Grayscale PWM Control:** 4096 steps (12-bit)  
- **Data Transfer Rate:** Up to 30 MHz  
- **Package:** HTSSOP-28 (PWP)  
- **Operating Temperature:** -40°C to +85°C  

### **Descriptions:**
- The TLC5940PWP is designed for LED display applications, providing precise current control and grayscale modulation.  
- It includes dot correction for brightness uniformity and grayscale PWM for smooth dimming.  
- The device supports daisy-chaining for multiple ICs in larger LED arrays.  

### **Features:**
- **Constant-Current Sink Outputs:** Ensures consistent LED brightness.  
- **Dot Correction:** Compensates for LED brightness variations.  
- **12-Bit Grayscale PWM:** Enables high-resolution brightness control.  
- **30 MHz Data Transfer:** Supports high-speed communication.  
- **Thermal Shutdown Protection:** Prevents overheating damage.  
- **Low Standby Current:** Reduces power consumption when idle.  

This information is based on the manufacturer's datasheet.
