Add To BomPCA9517ADP General Description
The PCA9517ADP is an I2C-bus buffer IC (Integrated Circuit) manufactured by NXP Semiconductors, which is now a part of ON Semiconductor. This IC is designed to provide I2C bus voltage level translation and buffering between two I2C bus segments operating at different voltage levels. It allows devices with different voltage levels to communicate on the same I2C bus without voltage compatibility issues.
Features
Bidirectional Voltage Translation: The PCA9517ADP can translate voltage levels between two I2C bus segments, typically between a lower-voltage I2C bus (e.g., 2.5V) and a higher-voltage I2C bus (e.g., 5V). This helps ensure that devices with different voltage requirements can communicate without damage.
Two Channels: The IC typically provides two bidirectional channels, allowing translation and buffering for two different I2C buses.
I2C Compatibility: It complies with the I2C standard and supports standard-mode (100 kbps) and fast-mode (400 kbps) I2C communication.
Bus Isolation: The PCA9517ADP offers bus isolation when the input supply voltage on either side is unpowered, preventing back-feeding of voltage.
Enable Pins: Each channel has an enable pin, which can be used to disconnect the channel when not needed, reducing power consumption.
Low Standby Current: The IC typically has low standby current, making it suitable for battery-powered or low-power applications.
ESD Protection: It may include ESD (Electrostatic Discharge) protection, which helps protect the device from static discharge events.
Package: The PCA9517ADP is available in various package options, including SOIC (Small Outline Integrated Circuit) and TSSOP (Thin Shrink Small Outline Package), which are suitable for surface-mount applications.
Application
Interfacing between microcontrollers, sensors, and other I2C devices operating at different voltage levels.
Bridging communication between legacy devices with higher voltage I2C buses and newer devices with lower voltage I2C buses.
Systems with multiple I2C buses operating at different voltage levels, such as mixed-voltage-level PCB designs.
