TCA9517DR Typical application Circuitry

TCA9517DR

The TCA9517DR is a level-translating I²C and SMBus repeater designed by Texas Instruments. This integrated circuit (IC) serves as a bidirectional buffer for I²C and SMBus systems, facilitating communication between devices that operate at different voltage levels. Here's a detailed description of the TCA9517DR:

1. I²C and SMBus Repeater: The TCA9517DR is specifically designed to act as a repeater for I²C or SMBus data (SDA) and clock (SCL) lines, providing level translation and enhancing signal integrity across the bus.

2. Level Translation: This IC translates signals between two voltage domains. It supports voltage translation between a VCCA side (1.65 V to 3.6 V) and a VCCB side (2.3 V to 5.5 V), enabling seamless communication between devices with different supply voltages.

3. Bidirectional Buffering: The TCA9517DR provides bidirectional buffering for both data and clock lines, ensuring proper signal integrity, especially in long-distance or high-capacitance bus lines.

4. Hot Insertion: The IC supports hot insertion, allowing components to be added or removed from the bus while the system is powered upwithout causing data corruption or glitches.

5. Pre-Charged Bus: The repeater pre-charges the bus capacitance of the SDA and SCL lines using pull-upresistors to prevent glitches on the bus during hot insertion.

6. High-Impedance SDA, SCL Pins: When the IC is unpowered, the SDA and SCL pins maintain a high-impedance state, ensuring that the TCA9517DR does not load the bus.

7. Enable Pin (EN): The TCA9517DR features an enable pin that can be used to activate or deactivate the device. When disabled, the repeater enters a low-power standby mode and the I/O pins are isolated.

8. Package: The TCA9517DR is typically available in an SOIC (Small Outline Integrated Circuit) package, which is suitable for a variety of applications.

9. Applications: The IC is ideal for applications requiring I²C or SMBus communication between devices with different supply voltages, such as multi-voltage systems, industrial equipment, embedded systems, and consumer electronics.

10. Datasheet: For detailed specifications, pin configurations, electrical characteristics, and application notes, it is recommended to consult the datasheet of the TCA9517DR, which can be obtained from Texas Instruments' website or from authorized distributors.

In summary, the TCA9517DR is a level-translating I²C and SMBus repeater that offers bidirectional buffering, signal integrity enhancement, and voltage level translation, making it a valuable component in systems that require robust communication between devices operating at different voltages.
