Description and Introduction

16 Channel Constant Current LED Driver with LED Open Detection 24-SSOP -40 to 85 The TLC5928DBQR is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Number of Channels:** 16  
- **Output Current:** 5 mA to 120 mA per channel (adjustable via external resistor)  
- **Supply Voltage (VCC):** 3 V to 5.5 V  
- **Logic Input Voltage:** 3 V to 5.5 V (TTL/CMOS compatible)  
- **Data Transfer Rate:** Up to 30 MHz  
- **Package:** SSOP-24 (DBQ)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The TLC5928DBQR is designed for driving LEDs with constant current, ensuring uniform brightness.  
- It includes a shift register and data latch for serial data input.  
- Each channel has an independent current setting via an external resistor.  
- Supports cascading for driving more than 16 LEDs.  

### **Features:**
- **Constant-Current Output:** Reduces LED brightness variations.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Open-Circuit Detection:** Flags open LED connections.  
- **Low Standby Current:** Reduces power consumption when idle.  
- **Schmitt-Trigger Inputs:** Improves noise immunity.  
- **Cascadable:** Multiple devices can be daisy-chained for larger LED arrays.  

This information is based on TI's official datasheet for the TLC5928DBQR.
