Description and Introduction

Low-Voltage 7-Bit I2C and SMBus LED Driver With Intensity Control and Shutdown 14-TSSOP -40 to 85 The TCA6507PWR is a 7-bit I²C and SMBus I/O expander manufactured by Texas Instruments (TI). Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Pb-Free Specifications:**  
- The device is **Pb-free (RoHS compliant)**.  
- It meets the requirements of the Restriction of Hazardous Substances (RoHS) directive.  

### **Descriptions:**  
- The TCA6507PWR is a **7-bit I²C/SMBus I/O expander** with **interrupt output and configuration registers**.  
- It provides **general-purpose remote I/O expansion** for most microcontroller families via the I²C interface.  
- Features **three programmable LED dimming/blinking modes** for output control.  
- Supports **100 kHz (standard) and 400 kHz (fast) I²C communication**.  

### **Features:**  
- **7 programmable GPIO pins** with configurable push-pull or open-drain outputs.  
- **Hardware dimming/blinking control** for LED driving.  
- **Interrupt output** to signal input state changes.  
- **Wide operating voltage range**: 1.65 V to 5.5 V.  
- **Low standby current consumption**.  
- **Packaging**: TSSOP-16 (PWR suffix).  
- **I²C address selection** with three hardware pins (supports up to eight devices on the same bus).  

This information is strictly based on the manufacturer's specifications.
