MIC2077-1BM

Overview

The MIC2077-1BM is a quad high-side MOSFET switch optimized for general-purpose power distribution requiring circuit protection. It operates within a supply voltage range of 2.7V to 5.5V and provides an output current limit of 900mA per channel. The device features a maximum on-resistance of 150mΩ, a maximum turn-on time of 5ms, and a maximum idle time of 100μs. It supports operation temperatures from -40°C to +85°C and is available in a 16-pin SOIC package.

Feature Summary

• Quad high-side MOSFET architecture designed for USB power distribution applications
• Integrated circuit protection including fixed current limiting and thermal shutdown
• Controlled slew rate functionality to minimize inrush current during turn-on

Applications

• General-purpose power distribution systems requiring circuit protection
• USB peripheral power switching and management
• Battery-powered equipment load drivers

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape-and-reel status. Confirm RoHS compliance status as historical data may vary by production batch. Ensure the source document explicitly identifies the manufacturer as Microchip Technology or its acquired entities like Micrel Semiconductor to validate component authenticity.

Selection Notes

Select this component when four independent high-side switches are required with integrated fault protection. The 900mA current limit suits standard USB loads. Consider the 150mΩ on-resistance for power dissipation calculations. Verify that the 2.7V minimum operating voltage aligns with the system's logic levels and supply rails.

Part Context

The MIC2077 series complements the MIC2027 family, offering higher current capabilities. While the MIC2027 typically limits at 500mA, the MIC2077 increases this to 900mA. Both share similar quad-channel architectures and protection features, making them suitable for multi-port power distribution designs where space efficiency is critical.

Replacement Considerations

MIC2077-1YWM is a documented direct substitute within the same product family.
