Description and Introduction

16 Channel LED Driver with Dot Correction and Grayscale PWM Control 28-HTSSOP The TLC5941PWPR is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

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

### **Descriptions:**  
The TLC5941PWPR is designed for LED driving applications requiring high-precision current control. It features individual PWM dimming and dot correction for uniform brightness across multiple LEDs. The device communicates via a serial interface and supports daisy-chaining for expanded applications.  

### **Features:**  
- **Constant-Current Sink Outputs:** Ensures consistent LED brightness.  
- **12-Bit PWM Grayscale Control:** Provides smooth dimming with 4096 steps.  
- **6-Bit Dot Correction:** Compensates for LED brightness variations.  
- **Serial Data Interface:** Supports high-speed data transfer (up to 30 MHz).  
- **Thermal Shutdown & Open-LED Detection:** Protects the device from faults.  
- **Daisy-Chaining Capability:** Allows control of multiple devices with a single interface.
