TCA9534PWR

Interface - I/O Expanders

The TCA9534PWR is an I/O expander focusing on digital interface applications that is designed to extend the user’s control options beyond the existing scope of interfaces. This component is widely used in applications ranging from automotive to industrial control. In addition, it is an ideal solution for situations where an increase in interface control is needed. This makes the component ideal for applications such as industrial automation, automotive drivers, HVAC, healthcare systems, and gaming applications.

Overview

The TCA9534PWR is a low-voltage, I/O expander that enables the user to extend their interface control ability. It is ideal for applications where an increase in control is needed but the available space does not allow for it. The component contains 10 pins that are all individually configurable for usage. These pins are supported via either an I2C or SMBus interface. In addition, the component offers a low voltage operation of 2.3V to 3.6V which is especially beneficial for automotive applications.

Applications

The TCA9534PWR has a wide range of applications mainly suited towards automotive and industrial type operations. Industrial automation, automotive drivers, HVAC, healthcare systems, and gaming applications are just some of the major applications it is commonly used. As mentioned earlier, it is highly beneficial due to its low voltage operation and extended interface control ability which makes it perfect for applications where space is limited, but the user needs to still have access to a wide range of options.

Working Principle

The TCA9534PWR is an I2C or SMBus compatible component. It is capable of transferring data efficiently to and from other components. It works by using the I2C or SMBus protocol for communication between two devices. The TCA9534PWR contains 10 pins which are individually configurable. Depending on the model and configuration the user has chosen, each pin can be set to input or output mode. The user can then configure the output modes and then connect the TCA9534PWR to other components to transfer data.

Conclusion

The TCA9534PWR is an I/O expander primarily used for automotive and industrial applications. It is very versatile and able to extend the user’s interface control beyond the scope of other devices. It operates on a low-voltage level and contains 10 individually configurable pins that are supported by an I2C or SMBus interface. This device is ideal for applications where an increase in control is needed, but space is limited.
