MIC2536-1YM

Overview

The MIC2536-1YM is a dual-channel high-side USB power switch IC manufactured by Microchip Technology. It operates within a load voltage range of 2.7V to 5.5V and provides a maximum output current of 150mA per channel. The device features a typical on-resistance (Rds On) of 400mΩ and supports a 1:2 input-to-output ratio with non-inverting logic inputs. Integrated fault protections include fixed current limiting, overtemperature shutdown, and reverse current blocking. Additional functional characteristics include controlled slew rates and status flags for monitoring. The component is housed in an 8-SOIC package and is rated for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Dual independent channels optimized for bus-powered USB applications
• Integrated fault protection including fixed current limit, overtemperature, and reverse current blocking
• Controlled slew rate functionality to minimize inrush current
• Status flag output for real-time operational monitoring

Applications

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

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging format, such as Tape and Reel (TR), Cut Tape (CT), or Digi-Reel® (DKR), matches your assembly requirements. Confirm that the 8-SOIC package dimensions align with your PCB footprint specifications. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain performance integrity. Cross-reference the manufacturer part number with official Microchip documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component when a dual-channel solution with integrated protection is required for low-current USB loads. The 150mA output rating suits peripherals with moderate power demands. Consider the 400mΩ on-resistance for efficiency calculations. The non-inverting input simplifies logic interfacing. Evaluate the need for status flags if system diagnostics are critical. Compare against single-channel alternatives if only one port is necessary, or higher-current variants like the MIC2547 if load requirements exceed 150mA.

Part Context

The MIC2536 belongs to Microchip's family of economical high-side power switches designed specifically for USB power distribution. It complements other models like the MIC2537 (quad channel) and MIC2547 (programmable current limit). This series addresses the need for compact, reliable power management in space-constrained designs. The device integrates essential protection features typically found in discrete solutions, reducing bill-of-materials complexity while ensuring robust operation in standard USB environments.

Replacement Considerations

Direct substitutes may include the MIC2536-1YM-TR for identical functionality in tape-and-reel packaging. For quad-channel requirements, consider the MIC2537-1YM. Higher current capacity options include the MIC2547-1YM. Verify pinout compatibility and thermal characteristics when transitioning between package types or channel counts.
