PCA9515ADGKR

The PCA9515ADGKR is a low-voltage, single-bus I2C bus switch from Texas Instruments. It is designed to provide a simple and efficient way to expand the I2C bus, allowing multiple I2C devices to be connected to a single master device.

Description:

The PCA9515ADGKR is a 1:2 I2C bus switch that allows a single I2C master to communicate with two I2C slaves. It features a low-voltage design (1.7V to 5.5V) and a small package size (6-pin WSON), making it well-suited for space-constrained applications.

Features:

• 1:2 I2C bus switch
• Low-voltage design (1.7V to 5.5V)
• Small package size (6-pin WSON)
• Supports standard mode (100kHz) and fast mode (400kHz) I2C communication
• 2.5mA typical current consumption in receive mode
• 1mA typical current consumption in transmit mode
• 3.5V to 5.5V I/O voltage range
• ESD protection up to ±4kV

Applications:

The PCA9515ADGKR is suitable for a wide range of applications that require I2C bus expansion, including:

1. Industrial control systems
2. Automotive infotainment systems
3. Consumer electronics
4. IoT devices
5. Smart home systems
6. Medical equipment
7. Robotics

In summary, the PCA9515ADGKR is a versatile and efficient I2C bus switch that can help engineers expand the I2C bus and connect multiple I2C devices to a single master device. Its low-voltage design, small package size, and support for both standard and fast mode I2C communication make it a popular choice for a variety of applications.
