Description and Introduction

16-Channel, 12-Bit PWM LED Driver with 6-Bit Dot Correction and Pre-Charge FET 28-HTSSOP -40 to 85 The TLC5944PWP is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments. Below are its specifications, descriptions, and features:

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

### **Descriptions:**  
- The TLC5944PWP is designed for LED display applications, providing precise current control and grayscale modulation.  
- It features dot correction to compensate for brightness variations between LEDs.  
- The device supports daisy-chaining for driving multiple LEDs in large display systems.  

### **Features:**  
- **Constant-Current Sink Outputs:** Ensures uniform LED brightness.  
- **PWM Grayscale Control:** 12-bit resolution for smooth dimming.  
- **Dot Correction:** 6-bit adjustment for brightness uniformity.  
- **Serial Data Interface:** Supports high-speed data transfer (30 MHz).  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Open-LED Detection:** Identifies faulty or disconnected LEDs.  
- **Low-Power Standby Mode:** Reduces power consumption when idle.
