Overview
The UCS2114T-1-V/LX is a dual USB port power switch IC manufactured by Microchip Technology. It features two high-side switches with an I2C/SMBus interface for digital control. The device supports a load voltage range of 2.9V to 5.5V and delivers a maximum output current of 3A per channel. Typical on-resistance is 18 mOhms, with a maximum of 30 mOhms. Operating supply voltage ranges from 4.5V to 5.5V. It includes fixed current limit, overtemperature, overvoltage, and UVLO protection. The component is housed in a 20-VFQFN (3x3) package.
Feature Summary
- Dual high-side USB power switches with integrated current sensing capabilities
- Digital control via I2C and SMBus interfaces for precise configuration
- Comprehensive fault protection including fixed current limit, overtemperature, overvoltage, and under-voltage lockout
Applications
- Industrial automation control systems
- USB hub implementations requiring individual port management
- Portable electronic devices needing efficient power distribution
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging containing 3300 units, distinct from non-tape variants. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements for surface mount assembly processes. Ensure the ordering part number matches the exact package and temperature grade specifications required for the target design.
Selection Notes
Select this component when dual independent USB power paths with digital monitoring are required. The I2C interface allows dynamic adjustment of switch parameters. Consider the 3A current capability and low on-resistance for minimizing power loss. Verify compatibility with the system's logic voltage levels for the control interface signals.
Part Context
This part belongs to the UCS2114 family of USB power switches. It shares functional similarities with the UCS2114-1-V/LX but differs in packaging format. The T suffix denotes tape and reel delivery, suitable for automated pick-and-place manufacturing. It serves as a solution for managing multiple USB ports in compact form factors.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-reference options based on pinout compatibility, electrical specifications, and package dimensions if substitution is necessary.
