Details
The TCA9802DGKT is a high-performance dual-channel bidirectional buffer specifically designed for I2C bus and SMBus/PMBus systems. Its ability to perform bidirectional level shifting between low and high voltages, along with its internal current source on the B-side, sets it apart from other solutions. The TCA9802 also offers true buffering without using static voltage offset or incremental offset, ensuring low VOL on both A and B sides, thereby minimizing communication issues. With no power sequencing requirements and power supply dependencies, the TCA9802 provides system designers with additional flexibility in its application. Its inclusion in a four device family with varying current source strengths underscores its versatility and adaptability for a range of system requirements

FAQs
What is TCA9802DGKT?
The TCA9802DGKT is a dual-channel translating I2C bus buffer with a dual voltage level-shifting feature, designed by Texas Instruments. It is suitable for applications requiring bidirectional voltage translation between different I2C buses operating at different voltage levels, such as in mixed-voltage level I2C buses, or with other general-purpose I2C devices.
How Does TCA9802DGKT Work?
The TCA9802DGKT works by providing bidirectional voltage translation and isolation between two I2C bus sections operating at different voltage levels. It uses internal voltage level-shifting circuitry to ensure seamless communication between devices with different supply voltages. The device supports standard mode (100 kHz) and fast mode (400 kHz) I2C bus speeds.
How Many Pins does TCA9802DGKT have and What are the Functions of the Pinout Configuration?
The TCA9802DGKT is housed in a 8-pin VSSOP (Very Small Outline Package) package. The pinout configuration includes:
- OE: Output enable pin.
- A1, A2: Control input pins for device address selection.
- VCCA, VCCB: Power supply/input voltage pins for Bus A and Bus B, respectively.
- GND: Ground pin.
- SCL, SDA: I2C bus interface pins.
What are the Pros and Cons of TCA9802DGKT?
Pros:
- Voltage Translation: Provides bidirectional voltage translation between two I2C buses operating at different voltage levels.
- Simple Control: The device can be controlled through I2C bus pins for easy configuration and management.
- Space-Saving Package: The 8-pin VSSOP package is compact and suitable for space-constrained designs.
- Low Power Consumption: Operates with low power consumption, suitable for portable or battery-powered applications.
Cons:
- External Components: May require additional pull-up resistors for efficient I2C bus operation.
- Static-sensitive Handling: The VSSOP package requires appropriate handling to prevent electrostatic discharge (ESD) damage.
Are There Any Equivalents/Alternatives to TCA9802DGKT for Recommendation?
- The PCA9517 from NXP Semiconductors is a similar dual-channel translating I2C bus buffer with voltage shifting features.
- Alternatives to the TCA9802DGKT include the BSS138 from Infineon and the LSF0204 from ON Semiconductor.
