Overview
The MIC2077-1YM is a quad USB high-side power switch manufactured by Microchip Technology. It features four independent N-channel outputs in a 16-SOIC package. The device supports load voltages from 2.7V to 5.5V with a maximum output current of 500mA per channel. Typical on-resistance is 100 milliohms. It includes fixed current limiting, overtemperature protection, and UVLO. Operating temperature range is -40°C to +85°C.
Feature Summary
- Integrates four independent high-side N-channel MOSFET switches for USB power distribution
- Provides comprehensive fault protection including fixed current limit, thermal shutdown, and under-voltage lockout
- Features controlled slew rate to minimize inrush current and status flags for monitoring
Applications
- USB hub power distribution circuits
- Portable device power management systems
- Industrial control board peripheral switching
Procurement Notes
Verify the specific suffix '1YM' corresponds to the SOIC-16 package and standard tape-and-reel or cut-tape availability. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the manufacturer part number with official Microchip documentation to ensure correct revision history and pinout compatibility before finalizing procurement orders.
Selection Notes
Select this component when designing systems requiring four isolated high-side switches with integrated USB-compliant protection. It is suitable for applications needing low on-resistance and precise current limiting without external components. Consider the 16-SOIC footprint constraints and thermal dissipation capabilities relative to the total load current and ambient operating conditions.
Part Context
The MIC2077 series belongs to Microchip's family of optimized power distribution switches. These devices are designed specifically for general-purpose circuit protection in USB and other low-voltage applications. The MIC2077-1YM variant offers a quad-channel configuration, providing a compact solution for managing multiple loads within space-constrained electronic designs.
Replacement Considerations
The MIC2027-1YM is a documented alternative within the same product family offering similar quad-channel functionality. Verify pinout compatibility and electrical parameter alignment, particularly regarding current limits and on-resistance values, before substituting.
