Description and Introduction

16-Channel 12-bit PWM with 7-bit Dot Correction The TLC5942 is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Channels:** 16  
- **Output Current:** Adjustable (up to 120 mA per channel)  
- **Supply Voltage (VCC):** 3.0 V to 5.5 V  
- **Logic Voltage (VLOGIC):** 3.0 V to 5.5 V  
- **Dot Correction (DC):** 6-bit (64 steps)  
- **Grayscale (GS) PWM Control:** 12-bit (4096 steps)  
- **Data Transfer Rate:** Up to 30 MHz  
- **Thermal Shutdown Protection:** Yes  
- **Package Options:** HTSSOP-32, QFN-32  

### **Descriptions:**
- The TLC5942 is designed for LED driving applications requiring high precision and brightness control.  
- It features individual 12-bit PWM grayscale control and 6-bit dot correction for brightness adjustment.  
- The device includes an internal oscillator for PWM generation, eliminating the need for an external clock.  
- It supports daisy-chaining for multiple devices in a system.  

### **Features:**
- **Constant-Current Output:** Ensures uniform LED brightness.  
- **Dot Correction:** Compensates for LED-to-LED brightness variations.  
- **Grayscale PWM Control:** Provides smooth dimming with 12-bit resolution.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Serial Interface:** Supports SPI-compatible communication.  
- **Low-Power Standby Mode:** Reduces power consumption when inactive.
