NXP PCA9617ADPJ I2C-Bus Repeater

The NXP PCA9617ADPJ is a high-performance, robust I2C-bus repeater designed to provide bidirectional voltage-level translation with true bidirectional capability. This device is an essential component for systems that require communication between devices operating at different voltage levels, making it ideal for multi-voltage systems. The PCA9617ADPJ allows for the extension of the I2C-bus by buffering both the data (SDA) and the clock (SCL) lines, thus enabling the bus to span longer distances and connect more nodes.

Featuring a hot-swap capability, the PCA9617ADPJ ensures that the I2C-bus can remain operational even when nodes are dynamically added or removed, without the need for powering down the system. This feature is particularly useful in server farms, telecommunications, and modular systems where maintenance or upgrades require flexibility and minimal downtime.

The PCA9617ADPJ operates over a wide supply voltage range (2.3V to 5.5V) on both the A-side and B-side, which allows for level translation between 1.8V, 2.5V, 3.3V, and 5V I2C-bus or SMBus applications. This voltage flexibility makes it suitable for a variety of mixed-voltage systems, such as battery-powered devices and energy-efficient applications.

With its enhanced ESD protection, the PCA9617ADPJ is designed to withstand electrostatic discharges, ensuring reliability and longevity in harsh environments. This protection is essential for industrial and automotive applications where electrical noise and static discharges are common.

The device comes in a small, leadless HVQFN package with 8 pins, which is ideal for space-constrained applications. Its footprint is compatible with the standard SOT1115 footprint, providing ease of design and layout for PCB designers.

Overall, the NXP PCA9617ADPJ is a versatile, high-quality I2C-bus repeater that provides reliable, bidirectional voltage-level translation and bus buffering capabilities. Its robust design and feature set make it an excellent choice for a wide range of applications in the consumer, industrial, and automotive markets.
