USB3750A-2-A4-TR

Controllers Overview

The USB3750A-2-A4-TR is a USB 2.0 protection IC manufactured by Microchip Technology, designed for portable applications requiring battery charging detection and overcurrent protection. It features a dual SPST switch configuration with a maximum on-resistance of 10 Ohms per channel. The device operates within a supply voltage range of 2 V to 9 V and supports data bandwidth up to 1 GHz. It functions reliably across an operating temperature range from -40°C to +85°C. Typical quiescent current consumption is specified at 110 µA or 115 µA depending on the specific mode. The component is housed in a QFN-16 package suitable for surface mount installation.

Controllers Feature Summary

• Integrated battery charging detection capability for identifying connected power sources
• Dual single-pole single-throw (SPST) switches providing independent channel control
• Overcurrent protection mechanism to safeguard downstream USB ports
• Low power consumption design optimized for battery-operated devices

Controllers Applications

• Portable electronic devices requiring USB port protection
• Battery-powered systems needing automatic charger detection

Controllers Procurement Notes

Verify the exact ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and temperature grade specifications. Confirm that the QFN-16 package dimensions align with your PCB footprint requirements. Check for any recent product change notifications regarding assembly or material composition updates before finalizing procurement orders.

Controllers Selection Notes

Select this component when a dual-channel USB protection solution with integrated battery charging detection is required. Ensure the system voltage remains within the 2 V to 9 V operational range. Consider the 10 Ohm on-resistance impact on signal integrity if high-speed data transmission is critical. Verify that the QFN-16 thermal pad requirements are met by the board design.

Controllers Part Context

This part belongs to the USB3750A series of USB 2.0 protection ICs from Microchip Technology. It serves as a specialized interface component for managing USB connectivity and power delivery in compact mobile electronics. The A4 suffix typically denotes specific packaging and temperature rating variations within the broader product family.

Controllers Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Direct replacements must match the QFN-16 package, dual SPST configuration, and battery charging detection functionality. Generic USB switches lacking integrated detection features are not suitable substitutes.
