Description and Introduction

16 Channel LED Driver with Dot Correction and Grayscale PWM Control 32-VQFN The TLC5941RHBR is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Channels:** 16  
- **Output Current:** Adjustable (up to 120 mA per channel)  
- **Supply Voltage:** 3.0 V to 5.5 V  
- **Data Transfer Rate:** Up to 30 MHz  
- **Dot Correction:** 64-step (6-bit) adjustable per channel  
- **Grayscale Control:** 4096-step (12-bit) PWM per channel  
- **Package:** 32-pin VQFN (RHBR)  
- **Operating Temperature:** -40°C to +85°C  

### **Descriptions:**  
- The TLC5941RHBR is designed for LED driving applications requiring high brightness and precise current control.  
- It includes dot correction (DC) and grayscale pulse-width modulation (PWM) for uniform brightness and color accuracy.  
- Serial data interface allows daisy-chaining multiple devices.  
- Suitable for LED displays, signage, and backlighting applications.  

### **Features:**  
- **Constant Current Sink Outputs:** Ensures consistent LED brightness.  
- **Dot Correction:** Compensates for LED-to-LED variations.  
- **12-bit Grayscale PWM:** Provides smooth dimming and color control.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Serial Data Interface:** Supports high-speed data transfer.  
- **Low Power Consumption:** Optimized for energy-efficient designs.
