Description and Introduction

16-Channel, Constant-Current LED Driver without LED Open Detection 24-VQFN -40 to 85 The TLC59281RGER is a 16-channel constant-current sink LED driver manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Channels:** 16  
- **Output Current Range:** 3 mA to 45 mA per channel (adjustable via external resistor)  
- **Supply Voltage (VCC):** 3 V to 5.5 V  
- **Logic Input Voltage (VIN):** 3 V to 5.5 V  
- **Current Accuracy:** ±6% (channel-to-channel), ±3% (chip-to-chip)  
- **Data Transfer Rate:** Up to 30 MHz  
- **Package:** 24-pin VQFN (RGER)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Description:**  
The TLC59281RGER is designed for driving LEDs with constant-current outputs, ensuring uniform brightness. It features a serial-in, parallel-out shift register with latched outputs, allowing daisy-chaining for expanded applications. The device includes thermal shutdown and open-LED detection for protection.  

### **Features:**  
- **Constant-Current Sink Outputs:** 16 channels with adjustable current via a single external resistor.  
- **High-Speed Data Transfer:** Supports clock frequencies up to 30 MHz.  
- **Error Detection:** Open-LED detection and thermal shutdown for fault protection.  
- **Daisy-Chain Capability:** Cascadable for driving more LEDs.  
- **Low Power Consumption:** Optimized for energy-efficient designs.  
- **Compact Package:** 24-pin VQFN (4 mm × 4 mm) for space-constrained applications.  

This information is strictly factual from the TI datasheet. Let me know if you need further details.
