PI6ULS5V9511AUEX - I2C/SMBus Repeater/Buffer

The PI6ULS5V9511AUEX by Diodes Incorporated is a high-performance, low-power I2C/SMBus compatible repeater/buffer that ensures signal integrity in communication buses. This device is specifically designed to provide bidirectional buffering for both the data (SDA) and clock (SCL) lines, allowing the extension of an I2C/SMBus bus segment while maintaining system stability and reliability.

With its robust design, the PI6ULS5V9511AUEX is capable of strengthening signals to overcome long cable lengths and to connect more devices without signal degradation. The repeater/buffer allows for the isolation of capacitance and effectively handles bus contention scenarios, which is particularly useful in complex systems with multiple bus masters.

Key Features:

• Compatible with I2C and SMBus signals
• Supports standard (100kHz), fast (400kHz), and fast-plus (1MHz) I2C/SMBus operation
• Low standby current, making it suitable for battery-powered applications
• 5V tolerant I/O ports allowing interface with legacy devices
• Hot-swappable with no glitch on power-up
• Prevents SDA and SCL corruption during live board insertion and removal from backplane

Applications:

• Servers and Networking: Repeaters and hubs in complex data center infrastructure
• Consumer Electronics: Extending I2C/SMBus in home entertainment systems
• Industrial: Long-distance sensor communication and industrial control systems
• Automotive: I2C/SMBus signal buffering for in-vehicle networks

The PI6ULS5V9511AUEX is available in a compact, lead-free package that is RoHS compliant, ensuring environmental sustainability while providing the flexibility for use in a wide range of applications. Its advanced features and compatibility with various I2C/SMBus speeds make it an ideal choice for designers looking to improve their communication bus systems.

Whether you are working on server management, industrial automation, or consumer electronics, the PI6ULS5V9511AUEX offers a reliable solution for your I2C/SMBus signal integrity challenges.
