Overview
The UCS2113-1C-V/G4 is a dual USB port power switch IC from Microchip Technology, designed for high-current applications. It supports an operating supply voltage range of 2.9 V to 5.5 V and delivers up to 3 A continuous current per VBUS port. The device features a maximum on-resistance of 40 mOhms and operates within a temperature range of -40°C to +105°C. Packaged in a QFN-20 format, it includes precision overcurrent protection and is qualified under AEC-Q100 standards for automotive reliability.
Feature Summary
- Dual USB port configuration with increased current limit threshold
- Precision overcurrent protection mechanism
- Automotive-grade qualification (AEC-Q100)
- Low on-resistance for efficient power delivery
Applications
- Automotive infotainment systems
- USB charging hubs
- Industrial control interfaces
- High-power USB peripheral connections
Procurement Notes
Verify the specific suffix 'C' indicates the increased current limit variant compared to standard models. Confirm AEC-Q100 qualification status if automotive compliance is required. Check for RoHS compliance documentation. Ensure the QFN-20 package matches PCB footprint requirements. Validate lead-free status against environmental regulations.
Selection Notes
Select this component when dual-port high-current switching is needed with automotive reliability. Compare against UCS2112 series if lower current or different timing characteristics suffice. Consider UCS2113T variant for tape-and-reel packaging needs. Evaluate thermal dissipation capabilities given the 3A output capability. Verify input voltage compatibility with the 2.9V to 5.5V range.
Part Context
Part of the UCS2113 family of dual USB power switches. Related variants include UCS2113-2C-V/G4 and UCS2113T-1C-V/G4. Shares core architecture with UCS2112 but offers enhanced current handling. Designed for robust performance in demanding environments requiring precise power management.
Replacement Considerations
UCS2113-2C-V/G4 is a confirmed substitute within the same family. UCS2113T-1C-V/G4 offers identical electrical specifications with reel packaging instead of tube. Verify pinout compatibility before substitution.
