NXP PCA9517ATP,147 - I²C Bus Repeater

The NXP PCA9517ATP,147 is a robust I²C bus repeater designed to provide bidirectional voltage-level translation and buffering capabilities for I²C bus and SMBus applications. This device is an essential component for systems that require the extension of I²C signals over a longer distance or connection between devices with different voltage requirements.

Key Features

• Voltage Level Translation: The PCA9517ATP,147 allows for level shifting between 0.8V to 5.5V on the A-side and 2.7V to 5.5V on the B-side, making it compatible with a wide range of I²C devices and logic levels.
• Hot-Swap Capability: It supports hot insertion on the I²C-bus without corrupting the data traffic, enhancing the flexibility and reliability of the system design.
• Enhanced Signal Integrity: The device provides a strong drive capability on the output stages to boost signal integrity, especially useful in noisy environments or over long cable lengths.
• Low Standby Current: The PCA9517ATP,147 features a low standby current, contributing to energy-efficient designs.
• Lock-Up Free Operation: It ensures that the bus does not lock-up if the SDA or SCL lines are stuck LOW, thanks to its built-in timeout function.
• Package: Supplied in a TSSOP-8 package, it is compact and suitable for space-constrained applications.

Applications

The PCA9517ATP,147 is ideal for a variety of applications where I²C signal integrity and voltage-level translation are critical. These include:

• Industrial control systems
• Automotive networks
• Telecommunications infrastructure
• Data acquisition systems
• Consumer electronics
