Overview
The MIC2548A-1YMM-TR is a single high-side power switch IC optimized for USB power distribution. It features an N-channel MOSFET with a maximum on-resistance of 80mOhm and supports load voltages from 2.7V to 5.5V. The device provides programmable current limiting up to 1.5A, along with over-temperature protection and a status flag output. Packaged in an 8-pin MSOP, it operates within a temperature range suitable for standard commercial applications.
Feature Summary
- High-side N-channel configuration optimized for low-loss DC power switching
- Programmable current limit capability for precise load protection
- Integrated fault protection including over-temperature shutdown
- Status flag output for monitoring operational state
Applications
- USB power switching and distribution
- Load drivers for peripheral devices
- Power management in portable electronics
Procurement Notes
Verify the specific suffix 'YMM' confirms the 8-MSOP lead-free package and tape-and-reel delivery format. Ensure the 'A' designation aligns with required thermal or electrical specifications. Confirm RoHS compliance status matches project requirements before finalizing procurement orders.
Selection Notes
Select this component when a single-channel high-side switch with adjustable current limiting is required for 3.3V or 5V systems. Consider the 80mOhm on-resistance for efficiency needs and verify that the MSOP package fits the available PCB footprint constraints.
Part Context
This part belongs to the Microchip MIC2548A series of integrated high-side power switches. These devices are designed for applications requiring robust load protection and efficient power distribution, such as USB hubs and peripheral interfaces, offering a compact solution compared to discrete implementations.
Replacement Considerations
Direct substitutes may include other single-channel high-side switches with similar voltage ratings and current limits. Verify pinout compatibility and ensure equivalent thermal performance characteristics match the original design requirements.
