USB3803CI-1-GL-TR

Controllers Overview

The USB3803CI-1-GL-TR is a low-power, USB 2.0 hub controller featuring three downstream ports and an integrated bypass switch. It supports Full-Speed (12 Mb/s), Low-Speed (1.5 Mb/s), and High-Speed (480 Mb/s) data rates. The device operates within a temperature range of -40°C to +85°C and utilizes a 25-ball WLCS package with a 1.95mm x 1.95mm footprint and 0.4mm ball pitch. It includes internal 3.3V and 1.2V voltage regulators for single-supply operation, accepts external reference clocks of 12, 19.2, 26, or 38.4 MHz, and provides ±5kV HBM ESD protection.

Controllers Feature Summary

• Integrated USB 2.0 compatible 3-port hub with dedicated transaction translators per port for consistent full-speed throughput
• Advanced power saving features including 1 µA typical standby current and automatic port shutdown when disabled
• Supports USB Battery Charger Detection compliant with USB-IF Battery Charging 1.1 specification
• Configurable via serial I2C slave port for VID/PID/DID, string descriptors, and port mapping

Controllers Applications

• Mobile Phones
• Ultra Mobile PCs
• Tablet Computers
• Digital Still Cameras
• Portable Media Players

Controllers Procurement Notes

Verify the component against the official Microchip Technology datasheet DS00001691D. Confirm that the specific ordering suffix matches the required industrial temperature range (-40°C to +85°C) and package type. Ensure compatibility with system power supply requirements and reference clock frequencies before integration.

Controllers Selection Notes

Select this controller for portable applications requiring multiple USB connections with strict power constraints. Consider the integrated bypass switch for simplified connectivity in non-high-speed modes. Evaluate the need for I2C configuration flexibility versus default ROM settings. Verify that the 25-ball WLCS package fits the PCB layout constraints.

Controllers Part Context

The USB3803 family consists of USB3803C and USB3803Ci variants, differentiated by operating temperature ranges. The USB3803CI-1-GL-TR represents the industrial grade version optimized for mobile embedded systems. It shares core functionality with the commercial variant but extends operational reliability to colder environments.

Controllers Replacement Considerations

Public confirmed substitute part numbers include USB3803C and USB3803Ci. Other similar devices from the same manufacturer include USB3503 and USB2512B. Verify pinout and feature compatibility before substitution.
