PCA9306DCUTG4 Typical application Circuitry

PCA9306DCUTG4

A dual bidirectional I²C-bus and SMBus voltage-level translator, the PCA9306DCUTG4 is. It is appropriate for multi-voltage systems since it is made to facilitate smooth communication between devices running at various voltage levels over the same I²C or SMBus.

Features of PCA9306DCUTG4

1. Voltage Level Translation: The PCA9306DCUTG4 enables level translation between low-voltage (down to 0.9V) and higher-voltage (up to 5.5V) I²C-bus or SMBus devices.

2. Bidirectional Channels: It provides two bidirectional channels for data transfer (SDA and SCL lines).

3. No Direction-Control Signal: The device does not require a direction-control signal, simplifying application circuitry.

4. Low Standby Current: Contributes to power saving by drawing a low standby current.

Application Scenario: Multi-Voltage I²C Communication

In a system where a microcontroller operating at 3.3V needs to communicate with sensors operating at 1.8V over the I²C bus, the PCA9306DCUTG4 can facilitate this communication. Here's a detailed guide for connecting this in such a system:

Circuit Connection Details

1. Power Supply (VREF1 - Pin 1, GND1 - Pin 2, VREF2 - Pin 6, GND2 - Pin 5):

- Supplying Power to Both Sides: Connect VREF1 (Pin 1) to the 1.8V power domain and VREF2 (Pin 6) to the 3.3V power domain. Ground GND1 (Pin 2) and GND2 (Pin 5).

2. I²C Bus Connection (SDA1, SCL1 - Pins 3 and 4; SDA2, SCL2 - Pins 7 and 8):

- Connecting I²C Lines: Connect SDA1 and SCL1 (Pins 3 and 4) to the I²C data and clock lines of the 1.8V sensors. Similarly, connect SDA2 and SCL2 (Pins 7 and 8) to the I²C data and clock lines of the 3.3V microcontroller.

Design Considerations

When utilizing the PCA9306DCUTG4 in circuit design, take into account the following:

1. Voltage Compatibility: Verify that both sides of the system have voltage levels within the range that the PCA9306DCUTG4 can translate.

2. Pull-up Resistors: Properly size the pull-up resistors on the SDA and SCL lines for both voltage domains to ensure reliable communication.

3. PCB Layout: Minimize the length of the I²C lines and keep them away from high-speed or noisy signals to reduce the risk of communication errors.

4. Power Stability: Ensure stable power supplies for both VREF1 and VREF2 to maintain reliable voltage level translation.

By carefully considering these aspects and utilizing the functionalities and pin configurations of the PCA9306DCUTG4, one can effectively facilitate I²C communication between devices operating at different voltage levels. The PCA9306DCUTG4, with its voltage-level translation and bidirectional channels, is an excellent choice for complex multi-voltage I²C communication systems.
