Overview
The MIC2547-2BM is a dual high-side power switch IC from Microchip Technology, designed for low-loss DC power switching. It features two independent channels with adjustable current limits ranging from 100 mA to 1.5 A. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of up to 500 mA per channel. Key electrical parameters include a maximum on-resistance of 120 mΩ, a maximum turn-on time of 5 ms, and a maximum blanking time of 22 µs. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Dual programmable current limit protection for independent channel control
- Integrated fault protection including over-temperature and reverse current blocking
- Status flag output for real-time monitoring of operational conditions
Applications
- USB power distribution networks requiring precise current limiting
- Low-loss DC power switching in embedded systems
- Power management units needing dual-channel high-side switching
Procurement Notes
Verify the specific suffix 'BM' against the official Microchip datasheet to confirm package type and tape/reel specifications. Ensure compatibility with system voltage requirements (2.7V–5.5V) and thermal constraints (-40°C to +85°C). Cross-reference ordering information with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when dual-channel high-side switching with adjustable current limits is required. It is suitable for applications demanding low on-resistance and integrated fault protection. Consider the SOIC-16 package size and thermal dissipation capabilities relative to the expected load currents and ambient temperatures.
Part Context
The MIC2547 series includes variants like MIC2547-1YM and MIC2547-2YM, offering similar functionality in different packages or configurations. The MIC2547-2BM specifically denotes the dual-channel version in a 16-pin SOP package, optimized for space-constrained designs requiring robust power management.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Microchip's official cross-reference tools for compatible alternatives.
