Description and Introduction

16-Channel, 12-bit PWM LED Driver with 6-Bit Dot Correction 28-TSSOP -40 to 85 The TLC5946PWR is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Channels:** 16  
- **Output Current:** 5–60 mA per channel (adjustable via external resistor)  
- **Supply Voltage (VCC):** 3.0 V to 5.5 V  
- **Data Transfer Rate:** Up to 30 MHz  
- **Dot Correction:** 64 steps (6-bit) for brightness adjustment  
- **Grayscale Control:** 12-bit (4096 steps) PWM for each channel  
- **Package:** TSSOP-28 (PWR)  
- **Operating Temperature:** -40°C to +85°C  

### **Descriptions:**  
The TLC5946PWR is designed for LED display applications, providing precise current control and PWM dimming. It features dot correction for brightness uniformity and grayscale PWM for smooth dimming. The device supports daisy-chaining for multiple ICs in large LED matrices.  

### **Features:**  
- **Constant-Current Outputs:** Independent current setting per channel.  
- **Dot Correction:** Compensates for LED brightness variations.  
- **12-Bit Grayscale PWM:** Enables high-resolution dimming.  
- **30 MHz Data Transfer:** Supports high-speed serial communication.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Low-Power Standby Mode:** Reduces power consumption when idle.  

This information is sourced from the official TI datasheet for the TLC5946PWR.
