Description

The TCA9517ADGKR is a dual I2C bus buffer designed to extend the range and improve signal integrity of I2C communication in multi-master and multi-slave configurations. It operates with a supply voltage range of 1.65V to 5.5V, making it compatible with a variety of low-voltage applications. The device supports data rates up to 1 Mbps and allows for the reconnection of the I2C bus across different voltage levels, enhancing interoperability between components with varying supply voltages.
The TCA9517 features two separate I2C channels, enabling isolation between the bus segments. Its open-drain output configuration prevents bus contention, while built-in hysteresis enhances noise immunity. The device also has a low power consumption profile, which is beneficial for battery-operated devices.
Ideal applications include sensor networks, portable electronics, and any system requiring long-distance I2C communication. The TCA9517ADGKR is housed in a compact VQFN package, facilitating integration into space-constrained designs.

Features

The TCA9517ADGKR is a dual bidirectional I2C bus buffer designed for I2C applications with the following key features:
1. I2C Compatibility: Supports standard and fast-mode I2C communication.
2. Bus Buffering: Isolates I2C devices to improve signal integrity and reduce capacitance on the bus.
3. Dual Channel: Provides two independent buffers, allowing segregation of devices on the I2C bus.
4. Voltage Compatibility: Operates over a wide voltage range (1.2V to 5.5V), making it compatible with different logic levels.
5. Active Low Enable: Allows for easy control of the buffer operation via an enable pin.
6. High Speed: Supports data rates up to 1 Mbps.
7. Low Power Consumption: Designed for energy-efficient operation, suitable for battery-powered devices.
8. ESD Protection: Incorporates robust ESD protection to enhance reliability in various environments.
These features make the TCA9517ADGKR ideal for applications requiring I2C bus extension, such as sensors, microcontrollers, and other peripheral devices.

Package

The TCA9517ADGKR is packaged in a VQFN (Very Thin Quad Flat No-lead) 16-pin package, which is designed for surface mounting. This package type provides a compact footprint and is suitable for high-density applications.

Pinout

The TCA9517ADGKR is a dual bidirectional I2C bus and SMBus level shifter. It features a total of 8 pins. The primary functions of the pins are as follows:
1. VCCA (Pin 1) - Positive supply voltage for the low side (I2C bus on one side).
2. VCCB (Pin 2) - Positive supply voltage for the high side (I2C bus on the other side).
3. GND (Pin 3) - Ground connection.
4. SCL1 (Pin 4) - Low side SCL input/output.
5. SDA1 (Pin 5) - Low side SDA input/output.
6. SCL2 (Pin 6) - High side SCL input/output.
7. SDA2 (Pin 7) - High side SDA input/output.
8. N/C (Pin 8) - No connection.
This device allows for communication between I2C devices operating at different voltage levels, facilitating interoperability in mixed-voltage systems.
