UCS2113T-2C-V/G4

Overview

The UCS2113T-2C-V/G4 is a dual-channel USB power switch IC from Microchip Technology, designed for portable applications. It operates within a supply voltage range of 2.9 V to 5.5 V and features an on-resistance maximum of 40 mOhms. The device supports a DC switch current of 3 A with a typical operating supply current of 700 uA. Key timing parameters include a maximum turn-on time of 0.9 ms and a maximum idle time of 0.75 ms. It is housed in a QFN-20 package and functions as a dual USB port power switch with increased current limit threshold capabilities.

Feature Summary

• Dual-channel architecture providing independent control over two USB ports
• Integrated current sensing with increased current limit threshold for enhanced protection
• Low on-resistance design to minimize power loss during conduction
• Fast switching times supporting rapid connection and disconnection events

Applications

• Portable electronic devices requiring dual USB charging ports
• USB hub implementations needing per-port power management
• Battery-powered systems with strict current monitoring requirements
• Consumer electronics utilizing USB connectivity for data and power

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's official documentation to confirm the exact current limit threshold specifications. Ensure the QFN-20 package type matches your PCB footprint requirements. Cross-reference the RoHS compliance status directly with the latest datasheet revision. Confirm that the reel or cut tape packaging options align with your assembly line capabilities. Always validate the operating temperature range against your intended environmental conditions before finalizing procurement.

Selection Notes

Select this component when dual-port isolation with precise current monitoring is required. The increased current limit threshold distinguishes it from standard variants, offering robust overload protection. Consider the 700 uA quiescent current for battery-sensitive designs. The 40 mOhm on-resistance ensures efficient power delivery. Evaluate the QFN-20 package size relative to available board space constraints compared to alternative switch ICs.

Part Context

This part belongs to the UCS2113 series of USB dual-port power switches. It complements other variants like the UCS2113T-1C-V/G4 which may differ in current limit thresholds. The series is designed for modern USB applications requiring integrated protection and monitoring. Microchip Technology positions these ICs for cost-effective solutions in portable consumer electronics. The T-2C designation indicates specific thermal and electrical characteristics within the family.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided source material. Verify compatibility with direct competitors by matching the 40 mOhm on-resistance and 3 A current rating. Check if alternative dual-channel USB switches offer similar current limit thresholds. Ensure pinout compatibility if considering physical replacement without schematic changes.
