Overview
The MIC2027-1BWM is a quad USB power distribution switch manufactured by Microchip Technology, housed in a 16-SOIC package. It features four high-side N-channel outputs with a maximum current of 500mA per channel and a typical on-resistance of 100 milliohms. The device operates within a load voltage range of 2.7V to 5.5V and supports an input-to-output ratio of 2 x 1:2. It includes fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO) for fault protection. The component functions across a temperature range of -40°C to 85°C.
Feature Summary
- Integrates four high-side N-channel MOSFET switches optimized for general-purpose power distribution requiring circuit protection.
- Employs soft-start circuitry to minimize inrush current when driving highly capacitive loads.
- Features internally filtered transient current limit faults and asserts a status flag during overcurrent or thermal shutdown conditions.
Applications
- USB power distribution systems
- General-purpose load drivers
- Circuit protection applications
Procurement Notes
Verify the obsolete status of this specific part number before procurement planning. Confirm if the RoHS-compliant replacement MIC2027-1YWM meets your environmental requirements. Ensure that the non-RoHS designation does not conflict with regulatory standards for your target market. Check availability through authorized distributors or secondary markets as standard supply may be limited.
Selection Notes
Select this component for designs requiring four isolated high-side switches with integrated protection. The 100 milliohm on-resistance supports up to 500mA output current. Consider the MIC2027-1YWM if RoHS compliance is mandatory. Evaluate the 16-SOIC package dimensions against your PCB layout constraints. Verify that the 2.7V to 5.5V operating range aligns with your system's power supply specifications.
Part Context
The MIC2027 series comprises quad high-side MOSFET switches designed for power distribution. This model represents the non-RoHS variant in the 16-SOIC package. It shares functional similarities with the MIC2077 but lacks smart thermal shutdown capabilities. The series provides essential protection features like current limiting and thermal shutdown for protecting downstream loads.
Replacement Considerations
The MIC2027-1YWM is a direct replacement for the MIC2027-1BWM. The suffix change indicates RoHS compliance while maintaining identical electrical characteristics and pinout compatibility.
