MIC2075-1FBMM-TR

Overview

The MIC2075-1FBMM-TR is a high-side N-channel power distribution switch from Microchip Technology, housed in an 8-MSOP package. It supports a load voltage range of 2.7 V to 5.5 V with a maximum output current of 500 mA and a fixed current limit of 700 mA. The device features a typical on-resistance of 90 mOhms and a maximum of 140 mOhms. Key electrical parameters include a maximum turn-on time of 6 ms and a maximum blanking time of 100 us. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated circuit protection including fixed current limiting, overtemperature shutdown, and undervoltage lockout (UVLO).
• Controlled slew rate functionality to minimize inrush currents during switching events.
• Status flag output for monitoring fault conditions or operational state.

Applications

• USB port power distribution and protection
• General-purpose power bus switching
• Peripheral device power management

Procurement Notes

Verify the specific suffix 'FBMM' against official Microchip documentation to confirm pinout and feature variations compared to standard 'YMM' variants. Ensure compatibility with surface mount reflow processes given the MSOP-8 packaging. Confirm RoHS compliance status through the manufacturer's latest environmental declarations prior to procurement.

Selection Notes

Select this component for applications requiring robust high-side switching with integrated fault protection. The 500 mA continuous current rating suits low-power peripheral distribution. Consider the 90 mOhm typical Rds(on) for efficiency calculations. The 8-MSOP package is suitable for space-constrained designs requiring surface mount technology.

Part Context

This part belongs to the MIC2075 series of high-side MOSFET switches optimized for general-purpose power distribution. Originally developed by Micrel, now part of Microchip Technology, these devices provide circuit protection features essential for modern electronic systems. The series includes variants with different pinouts and feature sets to address diverse power management requirements.

FAQ

What is the function of the status flag?

The status flag provides a digital indication of the switch's operational state or fault conditions, such as overcurrent or overtemperature events.

How does the controlled slew rate benefit the circuit?

The controlled slew rate limits the rate of voltage change during turn-on, thereby reducing inrush currents that could destabilize the power supply rail.
