Overview
The MIC2549A-1BTS is a high-side power switch IC from Microchip Technology, designed for low-loss DC power switching and power distribution. It features a programmable current limit with an over-temperature latch protection mechanism. The device operates within a supply voltage range of 2.7 V to 5.5 V. It is housed in a compact SOIC-8 package, suitable for surface-mount applications.
Feature Summary
- Integrated high-side power switch optimized for low-loss DC power switching
- Programmable current limit functionality with over-temperature latch protection
- Designed for robust power management and distribution applications
Applications
- DC power switching systems
- Power distribution networks
- General power management circuits
Procurement Notes
Verify the specific suffix 'BTS' against the official Microchip datasheet to confirm the SOIC-8 package type and ensure it matches the required thermal and electrical specifications for the target design. Confirm RoHS compliance status directly with the manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when a high-side switch with programmable current limiting and thermal latch protection is required. Ensure the operating voltage range of 2.7 V to 5.5 V aligns with the system power rails. Consider the SOIC-8 package constraints for PCB layout and thermal dissipation requirements compared to alternative packages like TSSOP.
Part Context
This part belongs to the MIC2549A family of integrated high-side power switches. It shares core functional characteristics with other variants in the series, such as the MIC2549A-1YM-TR, but differs primarily in its physical packaging (SOIC-8 vs. TSSOP-14) and potentially specific pinout or thermal performance attributes defined by the package type.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by cross-referencing the pinout and electrical parameters of potential alternatives with the official MIC2549A-1BTS datasheet.
