Overview
The UCS2113T-1-V/G4 is a dual USB port power switch integrated circuit manufactured by Microchip Technology. It operates within a supply voltage range of 2.9 V to 5.5 V and features an on-chip current sensor for monitoring. The device supports USB 2.0 interfaces and includes two independent switches with a maximum on-resistance of 40 mOhms. It functions in temperatures from -40°C to +105°C, utilizes a QFN-20 package, and draws 700 uA of operating current.
Feature Summary
- Dual USB port power switching capability with integrated current sensing
- Supports USB 2.0 interface standards for reliable data and power transmission
- Low on-resistance design minimizes power loss during operation
Applications
- USB hub designs requiring dual-port power management
- Portable electronic devices needing efficient power switching
- Industrial equipment utilizing USB connectivity for control or data
Procurement Notes
Verify the specific suffix 'V/G4' against official Microchip documentation to confirm RoHS compliance and lead-free status. Ensure the QFN-20 package dimensions match your PCB footprint requirements. Confirm that the 2.9 V to 5.5 V operating voltage aligns with your system's power rails before finalizing procurement.
Selection Notes
Select this component when dual-channel USB power control with built-in current monitoring is required. It is suitable for applications needing low on-resistance to reduce heat generation. Consider the QFN-20 package size for space-constrained designs. Verify thermal performance under maximum load conditions given the 105°C upper temperature limit.
Part Context
This part belongs to the UCS2113 series of USB switch ICs from Microchip Technology. The series focuses on providing robust power switching solutions for USB peripherals. The UCS2113T-1 variant specifically denotes the standard current limit threshold configuration compared to other variants like the -1C model which offers increased thresholds.
Replacement Considerations
The UCS2113T-1C-V/G4 is a related variant offering an increased current limit threshold. Evaluate if the standard threshold of the UCS2113T-1-V/G4 meets your application needs or if the higher threshold of the -1C version is necessary for overload protection.
