Description and Introduction

16-Channel, 12-bit PWM LED Driver with 6-Bit Dot Correction 28-HTSSOP -40 to 85 The TLC5946PWP is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **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  
- **Package:** HTSSOP-28 (PWP)  
- **Operating Temperature:** -40°C to +85°C  
- **Dot Correction:** 6-bit (64 steps)  
- **Grayscale Control:** 12-bit (4096 steps)  
- **ESD Protection:** > 4 kV (HBM)  

### **Description:**
The TLC5946PWP is designed for LED display applications, providing precise current control and grayscale modulation. It features dot correction for brightness uniformity and PWM grayscale control for smooth dimming. The device supports daisy-chaining for multiple ICs in larger display systems.

### **Features:**
- **Constant-Current Sink Outputs:** 16 channels with adjustable current (via external resistor).  
- **Dot Correction:** Compensates for LED brightness variations.  
- **12-Bit Grayscale PWM:** Enables 4096 brightness levels per channel.  
- **Serial Data Interface:** Supports high-speed data transfer (up to 30 MHz).  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Open-Load Detection:** Identifies disconnected LEDs.  
- **Short-Circuit Detection:** Protects outputs from faults.  
- **Daisy-Chaining Capability:** Allows cascading multiple drivers.
