I/O Expanders

The TCA9534APWR is a low-power I2C bus switch from Texas Instruments. It is designed to enable communication between multiple I2C devices and a single I2C bus, reducing the number of I2C bus lines required and simplifying the system design.

Description:

The TCA9534APWR is a 4-port I2C bus switch that allows up to four I2C devices to share a single I2C bus. It is available in a small 16-pin TSSOP package and operates with a supply voltage range of 2.3V to 5.5V. The device is designed to be low-power and has a typical current consumption of only 1.1mA.

Features:

• 4-port I2C bus switch
• Supports I2C standard mode (100kHz) and fast mode (400kHz)
• Supports multiple I2C masters
• Independent control of each port
• Supports hot-swappable devices
• Low-power operation with typical current consumption of 1.1mA
• Small 16-pin TSSOP package
• Operating supply voltage range of 2.3V to 5.5V

Applications:

The TCA9534APWR is suitable for a wide range of applications where multiple I2C devices need to share a single I2C bus. Some potential applications include:

• Industrial control systems
• Home automation systems
• Automotive infotainment systems
• Sensor networks
• Medical equipment
• Consumer electronics

In summary, the TCA9534APWR is a low-power I2C bus switch that allows multiple I2C devices to share a single I2C bus, simplifying system design and reducing the number of I2C bus lines required. Its small form factor and low power consumption make it suitable for a wide range of applications.
