I/O Expanders

The TCA9535DBT 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 master. Here is a brief description of the device, its features, and potential applications:

Description:

The TCA9535DBT is a 1:5 multiplexer (MUX) that allows a single I2C bus master to communicate with up to five different I2C devices. It is a compact and low-power solution that can be used in various applications where multiple I2C devices need to share a single I2C bus.

Features:

1. 1:5 I2C bus multiplexer
2. Supports standard-mode I2C (100 kbps) and fast-mode I2C (400 kbps)
3. Low power consumption: 1.2 mA in active mode and 3.5 µA in standby mode
4. 2.3 V to 5.5 V supply voltage range
5. Small package size: 6-pin SC70-6
6. I2C address selection for easy configuration
7. General-purpose input/output (GPIO) pin for additional control options
8. Supports hot-swapping of I2C devices without bus reset
9. ESD protection up to ±4 kV (contact) and ±2 kV (air)

Applications:

1. Industrial control systems: Connect multiple sensors and actuators to a single microcontroller for efficient control and monitoring.
2. Consumer electronics: Manage multiple I2C devices in smartphones, tablets, and smart home devices.
3. Automotive systems: Enable communication between various I2C devices in automotive infotainment, safety, and control systems.
4. Medical equipment: Connect multiple I2C-based sensors and devices in medical monitoring and diagnostic equipment.
5. IoT devices: Facilitate communication between multiple I2C devices in Internet of Things (IoT) applications.

The TCA9535DBT is a versatile and low-power I2C bus switch that can be used in various applications where multiple I2C devices need to share a single I2C bus. Its compact size, low power consumption, and support for standard and fast-mode I2C make it an ideal choice for space-constrained and power-sensitive applications.
