Description and Introduction

16 Channel LED Driver with Dot Correction and Grayscale PWM Control 32-VQFN -40 to 85 The TLC5941RHBT is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **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 (VIO):** 3.0 V to 5.5 V  
- **Dot Correction:** 64-step (6-bit) adjustable brightness per channel  
- **Grayscale Control:** 12-bit PWM (4096 steps)  
- **Data Transfer Rate:** Up to 30 MHz  
- **Package:** 32-pin QFN (RHBT)  
- **Operating Temperature:** -40°C to +85°C  

### **Descriptions:**  
The TLC5941RHBT is designed for LED display and lighting 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 expanded LED control.  

### **Features:**  
- **Constant-Current Sink Outputs:** Ensures consistent LED brightness.  
- **Dot Correction:** Compensates for LED brightness variations.  
- **12-Bit Grayscale PWM:** Enables high-resolution dimming.  
- **Serial Interface:** Supports daisy-chaining for multiple devices.  
- **Thermal Shutdown & Open-LED Detection:** Protects the device and LEDs.  
- **Low-Power Standby Mode:** Reduces power consumption when inactive.  

This information is based solely on the manufacturer's datasheet and technical documentation.
