The PCA9518PWR is an IC component manufactured by Texas Instruments (TI). It is a level-translating repeater that operates at high speed (up to 400 kHz) and supports both I2C and SMBus protocols.
One of the key features of the PCA9518PWR is its bidirectional voltage-level shifting capability. It enables proper communication between devices that operate at different voltage levels. This functionality makes it ideal for connecting I2C devices with different voltage requirements, such as 3.3V and 5V systems.
The IC component features automatic direction sensing, which eliminates the need for additional control signals. It ensures seamless data transfer in both directions while simplifying the design process. Additionally, the PCA9518PWR prevents the bus lock-up by providing a low-impedance path between the SDA and SCL terminals when the VCC supply voltage is off.
Another notable feature of the PCA9518PWR is its support for multiple power supply options. It can be powered using a single supply voltage or separate supply voltages for both low-voltage and high-voltage sides. This flexibility allows designers to tailor the power setup according to their specific system requirements.
The PCA9518PWR also incorporates a programmable rise time control mechanism. This feature enables users to adjust the rise time of the SDA and SCL signals, enhancing signal integrity and performance in various system environments
