MIC2027-2BWM

Overview

The MIC2027-2BWM is a quad high-side MOSFET switch optimized for general-purpose power distribution requiring circuit protection. Manufactured by Microchip Technology, this component operates within a load voltage range of 2.7V to 5.5V and provides a maximum output current of 500mA per channel. It features an internal typical on-resistance of 100 milliohms and utilizes a 16-SOIC package. The device includes fixed current limiting, thermal shutdown, and under-voltage lockout (UVLO) for fault protection.

Feature Summary

• Integrated soft-start circuitry minimizes inrush current for highly capacitive loads
• Fault status flag indicates overcurrent and thermal shutdown conditions
• Internally filtered transient current limit faults prevent false triggering

Applications

• General-purpose power distribution systems
• USB power distribution switches
• Load drivers requiring circuit protection

Procurement Notes

Verify RoHS compliance status as the B suffix typically indicates non-RoHS specifications. Confirm end-of-life or obsolescence status with the manufacturer before finalizing design-in decisions. Ensure the specific package variant matches the PCB footprint requirements for the 16-SOIC form factor.

Selection Notes

Select this component when four independent high-side switches are required within a single integrated circuit. Consider the MIC2077 series if smart thermal shutdown behavior is preferred over standard latching protection. Evaluate the trade-off between the 100 milliohm on-resistance and the 500mA current capability against system power dissipation limits.

Part Context

This part belongs to the MIC2027 family of quad USB power distribution switches. It shares functional similarities with the MIC2077 but differs in thermal management logic. The device is designed for applications needing compact solutions for protecting multiple downstream loads from electrical faults.

Replacement Considerations

MIC2027-2YWM is a direct replacement offering RoHS compliance.
