Description and Introduction

16-Port, 5.5V Constant-Current LED Driver The MAX6969AUG+ is a 4-wire serial-interfaced LED driver manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (MAIXM)  
- **Type:** LED Driver  
- **Interface:** 4-Wire Serial (SPI™/QSPI™/MICROWIRE™ Compatible)  
- **Output Channels:** 20 constant-current sink outputs  
- **Output Current:** Adjustable (5mA to 40mA per output)  
- **Supply Voltage:** 3V to 5.5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 24-TSSOP  

### **Descriptions:**
The MAX6969AUG+ is a versatile LED driver designed for driving up to 20 LEDs with constant-current outputs. It features a 4-wire serial interface, making it compatible with SPI, QSPI, and MICROWIRE protocols. The device supports adjustable current settings and includes thermal shutdown protection.

### **Features:**
- **20 Constant-Current Outputs:** Each output can be individually controlled.  
- **Adjustable LED Current:** Programmable from 5mA to 40mA per output.  
- **4-Wire Serial Interface:** SPI/QSPI/MICROWIRE compatible.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Wide Operating Voltage Range:** 3V to 5.5V.  
- **Extended Temperature Range:** -40°C to +125°C.  
- **Compact Package:** 24-pin TSSOP for space-constrained applications.
