FUSB1500MHX

Overview

The FUSB1500MHX is a USB 2.0 Full-Speed and Low-Speed transceiver manufactured by Fairchild Semiconductor, now part of ON Semiconductor. It integrates charger detection capabilities for portable devices. The component operates within a supply voltage range of 3.0 V to 5.5 V. It supports data rates up to 12 Mbps for Full-Speed operation and 1.5 Mbps for Low-Speed mode. The device is housed in a 16-lead MLP (Mini Leadless Package) with dimensions of 4 mm x 4 mm. It includes internal pull-up resistors and ESD protection rated at ±2 kV HBM.

Feature Summary

• Integrates USB 2.0 physical layer transceiver with built-in charger detection logic
• Supports both Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) data transmission modes
• Includes internal pull-up resistors to simplify host and device connection configurations
• Provides electrostatic discharge (ESD) protection compliant with human body model standards

Applications

• Portable electronic devices requiring USB connectivity
• Charging stations and docks with automatic port detection
• Mobile phones and smartphones for data synchronization and charging
• Digital cameras and multimedia players with USB interfaces

Procurement Notes

Verify the manufacturer marking on the component, as Fairchild Semiconductor operations were acquired by ON Semiconductor. Ensure the ordering suffix matches the specific package variant required. Confirm RoHS compliance status through official datasheets or distributor documentation before procurement.

Selection Notes

Select this component when a compact USB 2.0 transceiver with integrated charger detection is needed. The 16-MLP package suits space-constrained designs. Verify that the operating voltage range aligns with the system power supply. Consider pin compatibility if replacing legacy USB PHY components in existing layouts.

Part Context

The FUSB1500 series belongs to Fairchild's portfolio of USB interface solutions designed for mobile and consumer electronics. This specific part number denotes the MLP package variant. The series focuses on simplifying USB implementation by combining physical layer functions with detection logic in a single small form factor.

Replacement Considerations

Direct substitutes include the FUSB1500MHX from ON Semiconductor, which maintains functional equivalence after the acquisition. Verify pin-to-pin compatibility and electrical specifications against the original datasheet before substitution.
