MIC2536-1YM-TR

Overview

The MIC2536-1YM-TR is a dual-channel high-side USB power switch manufactured by Microchip Technology. It operates within a supply voltage range of 2.7V to 5.5V and features an N-channel output configuration with a typical on-resistance of 400 milliohms. The device provides a maximum output current of 150mA per channel and includes fixed current limiting, overtemperature protection, and reverse current blocking. Packaged in an 8-SOIC surface-mount enclosure, it supports non-inverted input logic and offers controlled slew rates alongside status flags for fault indication.

Feature Summary

• Dual independent channels optimized for bus-powered USB applications
• Integrated fixed current limit and thermal shutdown protection
• Reverse current blocking capability prevents backflow
• Controlled slew rate minimizes inrush current during turn-on

Applications

• Bus-powered Universal Serial Bus (USB) peripheral devices
• Portable consumer electronics requiring power distribution
• Industrial control systems with USB connectivity
• Embedded systems needing protected high-side switching

Procurement Notes

Verify the complete part number MIC2536-1YM-TR against the manufacturer datasheet to ensure correct suffix alignment. Confirm that the 8-SOIC package dimensions match the PCB footprint requirements. Check RoHS compliance status and moisture sensitivity level specifications prior to assembly. Ensure the operating temperature range aligns with the intended environmental conditions.

Selection Notes

Select this component when a dual-channel solution is required for low-current USB loads. The 150mA limit suits small peripherals rather than high-power hubs. Consider the 400mOhm resistance for efficiency calculations. The SOIC package facilitates automated surface-mount assembly. Evaluate the need for status flags if fault monitoring is critical to system design.

Part Context

This device belongs to the MIC2536 family of power distribution switches designed specifically for USB interfaces. It replaces discrete MOSFET solutions by integrating protection logic into a compact package. The series targets cost-sensitive applications where space and component count are constrained while maintaining reliable power management for connected peripherals.

Replacement Considerations

Direct substitutes include other dual-channel USB switches from Microchip such as the MIC2026 or MIC2537 families. Verify pin compatibility and electrical parameters before substitution. Alternative manufacturers may offer similar functions but require thorough validation of interface timing and protection thresholds.
