Description and Introduction

Low-voltage 16-bit constant current LED sink driver with auto-power saving The STP16CPS05 is a low-voltage 16-bit constant-current LED sink driver manufactured by STMicroelectronics (STM).  

### **Specifications:**  
- **Output Current:** 5 mA to 90 mA per channel (adjustable via external resistor)  
- **Supply Voltage (VDD):** 3 V to 5.5 V  
- **Logic Input Voltage (VIH/VIL):** Compatible with 3.3 V and 5 V logic  
- **Output Voltage (VOUT):** Up to 17 V  
- **Data Shift Frequency:** Up to 30 MHz  
- **Power Dissipation:** 1.5 W (max)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-24  

### **Descriptions:**  
- The STP16CPS05 is designed for LED driving applications, providing constant current to each output channel.  
- It features a serial data input/output interface for cascading multiple devices.  
- Includes thermal shutdown and open-load detection for protection.  
- Suitable for LED displays, signage, and backlighting applications.  

### **Features:**  
- 16 constant-current output channels  
- Adjustable output current via external resistor  
- Serial data interface with clock and data latch  
- Error detection (open LED condition)  
- Thermal shutdown protection  
- Low standby current  
- Compatible with 3.3 V and 5 V logic levels  
- ESD protection (2 kV HBM)  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official STMicroelectronics documentation.
