Interface - Analog Switches - Special Purpose, are analog switches devices capable of controlling external signals. The PI3USB221AZWEX is an example of one of these devices. It is used to enable and dasible USB devices connected to a computer as required. It’s ideal for use in applications when extra flexibility is required.

Overview

The PI3USB221AZWEX is an interface switch for USB Type A and B port applications, with two switching channels and two enable/disable pins. It is designed to allow data communication in applications requiring maximum portability. It is the ideal choice for applications where the user requires the flexibility to disconnect and reconnect a USB device as needed.

The device is also ideal for applications where data is transferred between two hosts or a host and a device. The PI3USB221AZWEX enables bi-directional data transfer, making it an excellent choice for applications where bi-directional data transfer is required. It also permits up to 16 devices to be connected simultaneously, providing a flexible solution for situations where multiple devices need to be connected.

Features

• Bi-directional data transfer
• USB 2.0 compatible
• Two switching channels
• Up to 16 devices can be connected simultaneously
• 2.5V to 3.6V operating voltage range
• Supports UART and PIO communication
• Low standby operating current
• Low switch on resistance

Application Fields

The PI3USB221AZWEX is ideal for use in consumer and industrial applications such as point-of-sale terminals, consumer electronic systems, industrial control systems and portable transducers. It is also a useful device for applications that require bi-directional data transfer, such as printers and HD Video cameras. This device can be used to enable and disable multiple USB devices as needed, making it an excellent choice for applications requiring extreme flexibility.

Working Principle

The PI3USB221AZWEX works on the principle of interrupt control. It uses two switching channels and two enable/disable pins to enable and disable USB devices. The device supports UART and PIO communication, allowing it to be used in a variety of applications. The device can operate over a wide voltage range, supporting up to 3.6V, and also has low standby operating currents and low switch on resistance.

The device is based on a single-transistor architecture, which allows for fast switching between the two switching channels. This allows the device to be used in applications where the user requires maximum portability. The device also supports multiple devices, meaning that it can support up to 16 devices at once.

The device is designed to be used in a wide range of applications, from consumer electronics to industrial control systems. Its flexibility makes it an ideal choice for applications requiring bi-directional data transfer and USB portability. It is also ideal for applications that require multiple devices to be connected, or for users that require the flexibility to disconnect and reconnect a USB device as needed.
