MIC2075-2YM-TR

Overview

The MIC2075-2YM-TR is a single-channel high-side USB power switch IC manufactured by Microchip Technology. It operates within a supply voltage range of 2.7 V to 5.5 V and delivers a continuous output current of 500 mA with a fixed current limit of 700 mA. The device features a maximum on-resistance of 140 mΩ and utilizes an 8-pin SOIC-N surface-mount package. It includes integrated fault protection mechanisms such as thermal shutdown, under-voltage lockout, and a status flag output with a 3 ms filter to prevent false triggering.

Feature Summary

• Integrates soft-start circuitry to minimize inrush currents during capacitive load connections
• Provides intelligent thermal shutdown in breaker mode, latching the output off until the fault condition is resolved
• Features a status flag output with a 3 ms filtering mechanism to ensure reliable fault detection
• Supports reverse current blocking to prevent backflow through the internal body diode

Applications

• USB peripheral power distribution and hot-plug applications
• Laptop and notebook computer power management systems
• Personal Digital Assistant (PDA) power circuits
• PC Card and ExpressCard hot-swap interfaces

Procurement Notes

Verify that the ordering suffix matches the required configuration, specifically the active-low enable logic indicated by the '2' designation. Confirm the MSOP or SOIC package variant aligns with the PCB footprint requirements. Ensure compliance with RoHS directives and check moisture sensitivity levels for proper storage handling prior to assembly.

Selection Notes

Select this component when a single-channel high-side switch with precise current limiting is required for USB or general power distribution. It is suitable for designs needing integrated thermal protection with automatic recovery or latching behavior. Consider alternative pinouts if the specific enable polarity or package dimensions do not match the existing layout constraints.

Part Context

This part belongs to the MIC2025/MIC2075 family of high-side MOSFET switches designed for general-purpose power distribution. The MIC2075 series distinguishes itself with advanced thermal management features compared to basic switches. It serves as a critical protection element in portable electronics, ensuring system stability against overcurrent and overheating events.

Replacement Considerations

Direct substitutes include MIC2075-1YM-TR for active-high enable logic or MIC2075-2YMM-TR for MSOP packaging. Cross-reference with MIC2025-2YM-TR if higher current capacity is acceptable, noting differences in thermal latch behavior.
