Overview
The UCS2113-2-V/G4 is a dual-port USB power switch IC manufactured by Microchip Technology. It integrates two independent high-side switches with current sensing capabilities for USB applications. The device operates within a supply voltage range of 2.9 V to 5.5 V and supports a maximum DC switch current of 3 A. Key electrical parameters include a maximum on-state resistance of 40 mOhms, a maximum operating time of 0.9 ms, and a maximum idle time of 0.75 ms. The component functions across an extended temperature range from -40°C to +105°C and consumes a typical quiescent current of 700 µA. It is housed in a QFN-20 surface-mount package.
Feature Summary
- Integrates dual independent high-side power switches with built-in current monitoring functionality
- Provides enhanced protection through increased current limit threshold configuration options
- Supports fast switching transitions with defined operating and idle time characteristics
Applications
- Dual-port USB hub power distribution systems
- Portable electronic devices requiring per-port power management
- Industrial control interfaces utilizing USB connectivity
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm pinout compatibility and thermal performance specifications. Ensure the procurement channel provides valid RoHS compliance certificates and moisture sensitivity level (MSL) data prior to assembly. Cross-reference the manufacturer part number with the latest datasheet revision to validate operational parameters and packaging details.
Selection Notes
Select this component when dual-channel USB power switching with integrated current sensing is required. Compare against the UCS2113T variant if reel packaging is preferred over tube packaging for automated assembly lines. Evaluate the UCS2113-2C variant if a higher current limit threshold is necessary for specific load protection requirements.
Part Context
This device belongs to the UCS2113 series of USB dual-port power switches. It serves as a specialized solution for managing power delivery in multi-port USB architectures. The series emphasizes compact integration of switching and monitoring functions within a single QFN-20 package, facilitating efficient board space utilization in modern electronic designs.
Replacement Considerations
UCS2113T-2-V/G4 offers identical electrical specifications but utilizes tape-and-reel packaging instead of tubes. UCS2113-2C-V/G4 provides an increased current limit threshold while maintaining the same package and core functionality.
