概述

Description

The TCA9800DGKR is a specialized I²C bus buffer manufactured by Texas Instruments. It is designed to facilitate communication between I²C devices that operate at different voltage levels, effectively acting as a level shifter. A standout feature of the TCA9800DGKR is its ability to support dual voltage nodes, allowing it to interface between a low-voltage device (as low as 0.8V) and a higher voltage device (up to 3.6V), without requiring direction control signals. This makes it highly suitable for multi-voltage systems.
The device also incorporates rise time accelerators on the SDA and SCL lines, which help maintain signal integrity over longer distances or in high-capacitance environments. It supports clock stretching and arbitration, maintaining compatibility with standard I²C protocols. The TCA9800DGKR is packaged in a compact VSSOP-8, making it ideal for space-constrained applications such as smartphones, tablets, and other portable electronics. Its robustness and reliability are further enhanced by features like hot-swap capability and glitch filtering, ensuring stable operation in dynamic environments.

Equivalent

The TCA9800DGKR is a specialized buffer/level translator for I2C and SMBus applications. Equivalent products include the PCA9306 from NXP, the TXS0102 from Texas Instruments, and the MAX3372 from Maxim Integrated. These alternatives provide similar functionality for voltage level translation and buffering in I2C applications. However, it's important to compare specific features and specifications to ensure compatibility with your particular application.

Features

The TCA9800DGKR is a bidirectional buffer designed for I2C and SMBus applications. It features an active-high, open-drain enable pin, allowing it to be enabled or disabled as needed. The device supports voltage translation between 0.8 V to 3.6 V on the A-side and 2.2 V to 5.5 V on the B-side, making it suitable for interfacing between devices operating at different voltages. It features rise time accelerators, which help improve signal integrity on the I2C lines, and it maintains a low offset voltage to ensure accurate signal transmission. The TCA9800 is characterized by its ability to isolate bus capacitance, which improves performance in systems with multiple devices. Additionally, it offers glitch suppression to avoid false signaling. The device is packaged in a compact VSSOP-8 package, making it ideal for space-constrained applications. Its high reliability and robust performance make it suitable for use in a wide range of consumer electronics, industrial, and automotive applications.

Pinout

The TCA9800DGKR is a 10-pin device designed by Texas Instruments, primarily used as a dual bidirectional I2C-bus and SMBus voltage-level translator with support for clock stretching. It is commonly used for translating the voltage levels between different sections of an I2C bus, allowing for communication between devices operating at different voltage levels. The pin configuration includes two sets of SDA and SCL lines (SDA1/SCL1 and SDA2/SCL2) for the two sides of the I2C bus, as well as power supply pins (VCC1 and VCC2) for each side, which define the reference voltage levels for translation. Additionally, it includes ground pins and a few other control pins to ensure proper operation. The device supports a wide range of VCC voltages, allowing for robust level translation in complex systems.

Manufacturer

The TCA9800DGKR is manufactured by Texas Instruments (TI), a prominent American technology company. Texas Instruments is well-known for designing and manufacturing semiconductors and various integrated circuits, which are used in a wide array of electronic devices and systems globally. TI is a leading company in the electronics industry, providing products that serve applications ranging from automotive and industrial systems to personal electronics and communications equipment.

Application

The TCA9800DGKR is a bidirectional I2C bus buffer designed to enhance communication between multiple I2C devices, particularly when signal integrity is crucial. Its primary application areas include consumer electronics, industrial automation, and automotive systems. In these fields, it aids in managing communication across extended distances or between different voltage levels, ensuring reliable data transfer. Common applications include smart home devices, IoT systems, and other embedded systems that require robust I2C communication. Its ability to isolate bus capacitance and provide level shifting makes it valuable in complex designs where signal quality must be maintained across diverse components.

Package

The TCA9800DGKR is packaged in an 8-pin VSSOP (Very Thin Shrink Small Outline Package) with the designation 'DGK.' This package type is compact, ideal for applications demanding space efficiency.
