Overview
The MIC94084YFT-TR is a single-channel high-side load switch manufactured by Microchip Technology. It features a P-channel output capable of delivering a maximum continuous current of 2A. The device operates within a load voltage range of 1.7V to 5.5V and utilizes an On/Off interface for control. Key electrical specifications include a typical on-resistance (RdsOn) of 67mΩ and a thermal resistance (θJA) of 140°C/W. It supports non-inverted logic enable signals and functions across an operating temperature range of -40°C to +125°C TJ.
Feature Summary
- High-side power distribution with P-channel architecture
- Controlled slew rate to minimize inrush current
- Integrated load release functionality
- Compact surface-mount packaging
Applications
- USB port protection and power management
- Battery-powered equipment load switching
- Peripheral power sequencing in embedded systems
- General-purpose high-side load switching
Procurement Notes
Verify the specific suffix YFT corresponds to the 4-TMLF package variant when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supply chain source is authorized to guarantee component authenticity and traceability. Check for any recent Production Change Notices regarding assembly sites or labeling updates before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a compact, low-resistance high-side switch. The 67mΩ on-resistance supports up to 2A output current efficiently. The 1.7V minimum operating voltage makes it suitable for low-voltage digital logic interfaces. Consider the 4-TMLF package dimensions for PCB layout constraints and thermal dissipation requirements in dense designs.
Part Context
This part belongs to the MIC9408x series of power switches from Microchip Technology. It is functionally similar to the MIC94085YFT-TR but may differ in specific current ratings or internal configurations. The series is designed for portable electronics and USB applications requiring efficient power management in small form factors.
Replacement Considerations
The MIC94085YFT-TR is a confirmed substitute within the same product family. Verify pinout compatibility and ensure the replacement meets the specific current and voltage requirements of the original design.
