Overview
The MIC2027-2BM-TR is a quad USB high-side power switch IC from Microchip Technology, designed for general-purpose power distribution requiring circuit protection. It features four independent outputs with an internal current limit of 900 mA and operates within a supply voltage range of 2.7 V to 5.5 V. The device is housed in a 16-pin SOIC package and supports an operating temperature range from -40°C to +85°C. It includes soft-start circuitry to minimize inrush current and provides thermal shutdown protection.
Feature Summary
- Integrates four independent high-side MOSFET switches optimized for USB power distribution applications
- Provides internal current limiting and thermal shutdown to protect both the device and connected loads
- Includes soft-start circuitry to manage inrush currents associated with highly capacitive loads
Applications
- General-purpose power distribution systems requiring circuit protection
- USB port power management and distribution
- Embedded systems needing isolated channel control with overcurrent protection
Procurement Notes
Verify that the specific suffix '2BM' corresponds to the narrow (150 mil) SOIC-16 package variant as documented in official Microchip specifications. Confirm RoHS compliance status directly through the manufacturer's datasheet or authorized distributor documentation, as regulatory status can vary by production batch and region. Ensure the ordering part number matches the exact package width and tape-and-reel configuration required for your assembly process.
Selection Notes
Select this component when designing circuits that require four independent channels of protected power switching with integrated fault management. It is suitable for applications where space constraints favor a 16-pin SOIC footprint over larger packages. Consider the 900 mA current limit and 2.7 V to 5.5 V input range to ensure compatibility with your system's voltage rails and load requirements without external protection components.
Part Context
The MIC2027 series belongs to Microchip's family of USB power distribution switches, offering integrated protection features to simplify design. This specific model provides quad-channel capability, allowing for compact multi-port designs. It competes in the market for low-cost, high-reliability power switches used in consumer electronics and industrial interfaces where robust fault handling is critical for system stability.
Replacement Considerations
Official documentation indicates that the obsolete MIC2077-2BM should be replaced with the MIC2077-2YM. Verify if the MIC2027-2BM-TR has a direct pin-compatible successor or if the MIC2027-2YWM-TR serves as the updated equivalent based on current Microchip product listings.
