The PCA9513ADP,118 is a robust I²C-bus repeater designed by NXP Semiconductors to extend the reach of I²C communication by buffering both the data (SDA) and the clock (SCL) lines. This allows the bus capacitance to be partitioned and the I²C-bus to be extended in range or to drive more I²C devices.

Key Features

• Hot Swappable: The PCA9513ADP,118 can be added to or removed from a powered system without turning the power off, providing flexibility and ease of maintenance.
• Level Shifting: This repeater can also act as a level shifter, enabling the connection of devices that operate at different voltages on the same I²C-bus, making it highly versatile for various system configurations.
• Low Standby Current: The device is optimized for power efficiency, with a low standby current that helps to minimize power consumption when the bus is idle.
• Noise Filtering: The PCA9513ADP,118 includes noise filtering on SDA and SCL inputs, which enhances the reliability of the bus communication in noisy environments.
• Robust Design: It is designed to tolerate high bus capacitance and electromagnetic interference, ensuring stable operation in industrial environments.

Applications

The NXP PCA9513ADP,118 is suitable for a wide range of applications, including:

• Extending the I²C-bus communication distance beyond the typical 400 pF bus capacitance limit.
• Connecting multiple devices with different voltage levels on the same I²C-bus.
• Improving I²C signal integrity in noisy environments.
• Server and telecom infrastructure, where hot-swappable capabilities are essential.

Package and Quality

The PCA9513ADP,118 comes in a TSSOP8 package, which is a space-saving option for PCB designs. NXP's commitment to quality ensures that this I²C-bus repeater meets the stringent industrial standards for performance and reliability.

Whether you are looking to extend the reach of your I²C-bus, integrate devices with different voltage levels, or simply require a more robust communication link, the PCA9513ADP,118 from NXP is an excellent choice for your design.
