Overview
The MIC2548-2YMM-TR is a single high-side power switch IC from Microchip Technology, designed for low-loss DC power switching. It features an N-channel MOSFET with a maximum on-resistance of 120 mΩ and supports output currents up to 500 mA. The device offers a programmable current limit ranging from 100 mA to 1.5 A, allowing precise protection settings. Operating within a supply voltage range of 2.7 V to 5.5 V, it includes a maximum run time of 5 ms and a maximum off time of 22 µs. The component is housed in an 8-pin MSOP package and operates reliably between -40°C and +85°C.
Feature Summary
- Integrates a high-side N-channel power switch optimized for low-loss DC applications
- Features fully programmable current limiting to protect loads from overcurrent conditions
- Includes internal timing controls for configurable run and off times
Applications
- Low-loss DC power switching systems
- Peripheral power management circuits
- Bus protection and distribution networks
Procurement Notes
Verify the specific suffix TR indicates tape and reel packaging when sourcing. Confirm the 8-MSOP package type matches your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental specifications. Cross-reference the datasheet DS20005725 for exact electrical characteristics before finalizing procurement.
Selection Notes
Select this component when a single-channel high-side switch with adjustable current limits is required. The 120 mΩ on-resistance minimizes power dissipation compared to standard switches. Consider the 2.7 V to 5.5 V input range for compatibility with various logic levels. The programmable current limit allows customization for different load profiles without external sensing resistors.
Part Context
This part belongs to the MIC2548 series of integrated high-side power switches. It shares architectural similarities with the MIC2544 but differs in channel configuration. The series is optimized for power management applications requiring efficient switching and robust protection features in compact packages.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternatives.
