Description and Introduction

16-Channel, 12-bit PWM LED Driver with 6-Bit Dot Correction 32-VQFN -40 to 85 The TLC5946RHBR 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:** Adjustable (up to 60 mA per channel)  
- **Supply Voltage:** 3.0 V to 5.5 V  
- **Data Transfer Rate:** Up to 30 MHz  
- **Dot Correction:** 6-bit (64 steps) per channel  
- **Grayscale PWM Control:** 12-bit (4096 steps)  
- **Package:** 32-pin VQFN (RHBR)  
- **Operating Temperature:** -40°C to +85°C  

### **Descriptions:**  
The TLC5946RHBR is designed for LED driving applications requiring high precision and brightness control. It includes dot correction for current accuracy and grayscale PWM for brightness adjustment. It communicates via a serial interface (SPI-compatible).  

### **Features:**  
- **Constant-Current Sink Outputs:** Ensures uniform LED brightness.  
- **Dot Correction:** Compensates for LED forward voltage variations.  
- **12-Bit Grayscale Control:** Provides smooth dimming.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Low Standby Current:** Reduces power consumption.  
- **Cascadable:** Supports daisy-chaining for multiple devices.  

This device is commonly used in LED displays, signage, and backlighting applications.
