Description and Introduction

16-Channel LED Driver w/DOT Correction & Pre-Charge FET The TLC5924 is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Channels:** 16  
- **Output Current:** Adjustable (up to 120 mA per channel)  
- **Supply Voltage (VCC):** 3 V to 5.5 V  
- **Logic Input Voltage (VIN):** 3 V to 5.5 V  
- **Data Transfer Rate:** Up to 30 MHz  
- **Power Dissipation:** 1.2 W (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** HTSSOP-28, TSSOP-28  

### **Descriptions:**  
- The TLC5924 is designed for driving LEDs with constant-current outputs, ensuring uniform brightness.  
- It includes a serial-in, parallel-out shift register and latched outputs for stable LED driving.  
- Each channel has an individually adjustable current setting via an external resistor.  
- Compatible with 3.3 V and 5 V logic systems.  

### **Features:**  
- **Constant-Current Outputs:** Reduces brightness variations between LEDs.  
- **High-Speed Data Transfer:** Supports up to 30 MHz clock frequency.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Open-Circuit Detection:** Helps identify faulty LED connections.  
- **Cascadable Design:** Multiple devices can be daisy-chained for larger LED arrays.  
- **Low Standby Current:** Reduces power consumption when inactive.  

For detailed electrical characteristics and application circuits, refer to the official TI datasheet.
