MIC2536-2YMM

Overview

The MIC2536-2YMM is a dual-channel USB high-side power switch IC designed for bus-powered Universal Serial Bus applications. It features two independently controlled N-channel outputs with a fixed current limit of 275 mA per channel and a maximum on-resistance of 400 mOhm. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an active-high enable logic interface. It is housed in an 8-pin MSOP package and functions reliably across a temperature range of -40°C to +85°C, providing integrated protection against overcurrent and thermal conditions.

Feature Summary

• Dual independent high-side channels optimized for USB power distribution
• Integrated fixed current limiting and thermal shutdown protection
• Controlled slew rate to minimize inrush current during activation
• Status flag output indicating fault or active state conditions

Applications

• Bus-powered USB hub circuits
• USB peripheral power management systems
• Portable electronic device power switching
• Industrial USB interface modules

Procurement Notes

Verify the specific suffix 'YMM' corresponds to the 8-MSOP package configuration when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the active-high enable logic aligns with your system control signals. Cross-reference the manufacturer datasheet for exact pinout and electrical characteristics prior to final design approval.

Selection Notes

Select this component for designs requiring dual isolated USB ports with built-in fault protection. The 275 mA current limit suits standard USB 2.0 downstream port requirements. Consider the 400 mOhm on-resistance impact on voltage drop at full load. The MSOP package offers a compact solution for space-constrained PCB layouts compared to larger packages.

Part Context

Part of the MIC2536 family of cost-effective power switches. The MIC2536 series provides simplified power management for USB applications by integrating control logic and protection features into a single small-footprint IC. It serves as a reliable alternative to discrete MOSFET solutions, reducing component count and board space while maintaining robust performance standards.

Replacement Considerations

MIC2536-1YMM is available as a parameter-equivalent alternative with identical electrical specifications but may differ in packaging or internal channel configuration details.
