Description and Introduction

16-BIT CONSTANT CURRENT LED SINK DRIVER The STP16C596 is a 16-bit constant current LED sink driver manufactured by STMicroelectronics.  

### **Key Specifications:**  
- **Output Current:** 8–90 mA per channel (adjustable via external resistor)  
- **Supply Voltage (VDD):** 3.0–5.5 V  
- **Output Voltage (VOUT):** Up to 17 V  
- **Data Transfer Rate:** Up to 30 MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** SO-24, TSSOP-24  

### **Descriptions:**  
- Designed for driving LEDs in display applications.  
- Features a 16-bit shift register with constant current outputs.  
- Includes an open-drain error flag for thermal shutdown detection.  
- Supports daisy-chaining for cascading multiple devices.  

### **Features:**  
- **16 Constant Current Outputs:** Adjustable via a single external resistor.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Error Flag Output:** Indicates overtemperature conditions.  
- **Schmitt Trigger Inputs:** Ensures noise immunity.  
- **Serial Data Interface:** Compatible with SPI and similar protocols.  
- **Low Power Consumption:** Suitable for battery-powered applications.  

This device is commonly used in LED displays, signage, and lighting control systems.
