PCA9517ADP,118 Typical application Circuitry

PCA9517ADP,118

The PCA9517ADP,118 is a level translating I2C-bus repeater chip. Its primary function is to enable I2C and SMBus communication between devices that operate at different voltage levels, facilitating data transfer across varied power domains. This chip is especially beneficial in systems that integrate components with mismatched voltage requirements.

PCA9517ADP,118 Application Scenarios:

1. Interfacing Between Different Voltage Domains: Commonly used in situations where a low-voltage microcontroller must communicate with higher-voltage I2C peripherals.

2. Mixed-Voltage I2C/SMBus Systems: Ideal for extending the I2C or SMBus in systems comprising devices operating at different voltage levels.

Key Features and Parameters:

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

2. Bidirectional Data Flow: Supports bidirectional communication, essential for I2C and SMBus protocols.

3. Compatible Voltage Range: Typically functions within standard I2C-bus voltage levels.

4. Preservation of Signal Integrity: Ensures stable signal transmission, even when translating between different voltage levels.

Circuit Connection Example: Linking a 3.3V Microcontroller with 5V I2C Devices

Overview: Utilizing PCA9517ADP,118 to interface a 3.3V microcontroller with 5V I2C devices in a mixed-voltage system.

1. Power Connections:

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

- VDD2 (pin 16) must be connected to the 5V supply of the I2C devices.

2. System Grounding:

- GND (pin 5) needs to be connected to the common ground of the entire system.

3. I2C Bus Configuration:

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

- SDA2 and SCL2 (pins 2 and 4, respectively) should be connected to the I2C lines of the 5V devices.

4. Installing Pull-Up Resistors:

- Fit suitable pull-up resistors to the SDA and SCL lines at both voltage levels, based on the operating voltage and I2C specifications.

Design Considerations:

1. Voltage Level Matching: Ensure that VDD1 and VDD2 are correctly matched with the operating voltages of the microcontroller and I2C devices.

2. Appropriate Pull-Up Resistor Selection: Opt for correct pull-up resistor values for each side of the translator, critical for stable I2C communication.

3. Overall Bus Capacitance: Consider the capacitance of the entire I2C bus, especially important due to the level translation.

4. Signal Integrity Maintenance: Focus on maintaining signal integrity across the different voltage levels.

In conclusion, the PCA9517ADP,118 is a key component in mixed-voltage I2C or SMBus systems, enabling communication between devices operating at different voltage levels. Its ability to translate voltage levels while preserving signal integrity is invaluable in systems that integrate 3.3V microcontrollers with 5V peripherals, ensuring seamless data transfer in diverse electronic applications.
