The USB3803CI-1-GL-TR is a part of the Interface - Controllers. It leverages 3.3V single supply operation and integrated USB transceiver, which can effectively reduce system cost. This article will speak about the application field and working principle of this model.

Application Field

The USB3803CI-1-GL-TR is an ideal solution for USB 2.0 High-Speed applications. It can be used in different fields, such as PCs, notebooks, video equipment and so on. The main applications for the device include:

• Power over USB (PoU) applications to charge and power mobile devices.
• Charging stations for mobile and handheld devices.
• Mobile computing and communication equipment.
• Industrial and automotive applications.
• High speed data transfer.

The device claims to be the smallest of its kind with a total operational bandwidth of 20 MHz, capable of transferring 480mbps of data.

Working Principle

The USB3803CI-1-GL-TR powers up USB devices and sets current limitations and enumerates them on demand. It also negotiates over the bus and return status information back to the host when a connection is made. It also provides advanced features like low power standby mode and soft-start, which can help protect devices against damage that could occur due to sudden current rise.

The IC consists of four main components:

• USB 2.0 High Speed Transceiver: The USB transceiver consists of the required elements from a high speed USB2.0, such as the analog transceiver, on-chip HUB function and PHY. This enables the device to provide a poweroutlet for the connected USB device.
• Smart Power Management: This IC has advanced power management capabilities to reduce power consumption and protect against potential damage from large instantaneous current rise.
• Integrated 22KΩ Pull-Up Resistance: The USB3803CI-1-GL-TR has an integrated 22KΩ pull-up resistance to simplify the host system design.
• Status indicators: The device has status LEDs that indicate power status and enable the user to check power status conveniently.

By employing the USB3803CI-1-GL-TR, designers can build configurations to apply USB power to supply the DC power necessary to support connected USB devices. This helps reduce the cost of application designs.

Conclusion

The USB3803CI-1-GL-TR is a part of the Interface - Controllers that uses a 3.3V single supply operation and integrated USB 2.0 transceiver. It is suitable for Power Over USB applications with a bandwidth of 20 MHz and capable of transferring 480mbps of data. By employing this device, designers can significantly reduce the cost of applications by supplying the needed DC power for connected USB devices.
