PCA9517ADP/DG,118 Typical application Circuitry

PCA9517ADP DG,118

The PCA9517ADP/DG,118 is a level-translating I2C-bus repeater. It is designed to provide bidirectional voltage-level translation and buffering for I2C-bus signals, which is essential for applications involving devices operating at different voltage levels. This chip is particularly useful in systems where I2C communication needs to occur between components that do not share the same voltage level.

Application Scenarios:

1. Interfacing Devices with Different Voltage Levels: The PCA9517ADP/DG,118 is extensively used in systems where a low-voltage microcontroller needs to communicate with higher-voltage I2C peripherals.

2. I2C Bus Extension in Mixed-Voltage Systems: It's also crucial in scenarios that require extending the I2C bus across devices with varying operating voltages.

Key Features and Parameters:

1. Voltage-Level Translation: The PCA9517ADP/DG,118 provides bidirectional voltage-level translation for I2C-bus signals.

2. Bidirectional Buffering: It supports bidirectional communication, which is vital for I2C and SMBus operations.

3. Voltage Range Flexibility: Typically compatible with standard I2C-bus voltage levels.

4. Signal Integrity Maintenance: Ensures stable signal transmission, even with level translation.

Circuit Connection Example: Connecting a 3.3V Microcontroller to 5V I2C Sensors

Overview: Employing PCA9517ADP/DG,118 for interfacing a 3.3V microcontroller with 5V I2C sensors in a mixed-voltage environment.

1. Power Supply Connection:

- VDD1 (pin 8) should be connected to the 3.3V power supply of the microcontroller.

- VDD2 (pin 16) must be linked to the 5V power supply of the I2C sensors.

2. Grounding the Circuit:

- GND (pin 5) needs to be tied to the system's common ground.

3. I2C Bus Configuration:

- SDA1 and SCL1 (pins 3 and 6, respectively) are connected to the I2C lines of the 3.3V microcontroller.

- SDA2 and SCL2 (pins 2 and 4, respectively) are linked to the I2C lines of the 5V sensors.

4. Setting Up Pull-Up Resistors:

- Attach appropriate pull-up resistors to the SDA and SCL lines for both the microcontroller and sensor sides, considering their respective voltage levels.

Design Considerations:

1. Ensuring Voltage Compatibility: Verify that VDD1 and VDD2 align with the microcontroller and sensors' operating voltages.

2. Pull-Up Resistor Calibration: Choose correct pull-up resistors for each side of the translator to maintain stable I2C communication.

3. Bus Capacitance Management: Account for the increased bus capacitance due to the level translation and extended bus.

4. Signal Integrity Assurance: Special attention should be given to maintaining signal integrity across the voltage-level translation.

In summary, the PCA9517ADP/DG,118 is crucial in applications requiring I2C communication between components with different operating voltage levels. Its ability to translate and buffer I2C signals while maintaining signal integrity is invaluable in mixed-voltage environments, such as systems combining 3.3V microcontrollers with 5V sensors.
