Overview
The MIC94161YCS-TR is a high-side load switch from Microchip Technology designed for power distribution applications. It operates within an input voltage range of 1.7V to 5.5V and supports a maximum output current of 3A. The device features a low on-resistance of 40mΩ (maximum) and utilizes a P-channel pass element. Key timing specifications include a maximum turn-on time of 10µs and a maximum turn-off time of 25µs. It is available in an 8-pin SOIC package and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- High-side topology with integrated reverse blocking capability
- Low on-resistance internal P-channel pass element
- Fast switching performance with defined turn-on and turn-off times
Applications
- Power distribution in portable electronic devices
- Load switching in industrial control systems
- Battery-powered equipment requiring efficient power management
Procurement Notes
Verify the specific suffix 'YCS-TR' corresponds to the SOIC-8 package and tape-and-reel packaging configuration as documented in the official Microchip datasheet. Confirm that the ordering part number matches the exact electrical characteristics and thermal specifications required for your design, ensuring compatibility with your PCB footprint and reflow soldering profile.
Selection Notes
Select this component when a high-side switch with reverse blocking is required for voltages between 1.7V and 5.5V. Consider the 3A current limit and 40mΩ on-resistance for efficiency calculations. Ensure the SOIC-8 package fits the board layout constraints and that the operating temperature range meets environmental requirements.
Part Context
This part belongs to the MIC9416x family of high-side load switches, which includes variants like the MIC94162, MIC94163, etc., differentiated by pinout or specific feature sets. The MIC94161 specifically offers reverse blocking protection, making it suitable for applications where back-powering must be prevented.
Replacement Considerations
Direct substitutes may include other parts from the MIC9416x family such as the MIC94162YCS-TR, provided the functional differences align with system requirements. Verify pin compatibility and electrical parameters before substitution.
