MIC2536-2BMM

Overview

The MIC2536-2BMM is a dual-channel USB power distribution switch manufactured by Microchip Technology. It operates within an input voltage range of 2.7V to 5.5V and provides independent control for each channel. The device features a typical on-resistance of 400mΩ and supports a minimum continuous load current of 150mA per channel. It is housed in an 8-pin MSOP package with tape and reel packaging. Key electrical characteristics include active-high enable logic, fixed current limiting, and over-temperature protection. The component functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual independently controlled channels optimized for bus-powered Universal Serial Bus applications
• Integrated fault protection including fixed current limiting and over-temperature shutdown
• Slew rate controlled output to minimize inrush current during turn-on

Applications

• Bus-powered Universal Serial Bus (USB) peripheral devices
• Power distribution switches in portable electronics
• Load drivers for low-power digital circuits

Procurement Notes

Verify the specific suffix 'BMM' corresponds to the 8-pin MSOP package and tape-and-reel delivery format. Confirm that the manufacturer designation aligns with Microchip Technology, noting historical lineage from Micrel Semiconductor. Ensure compliance requirements such as RoHS status are documented in the official datasheet for the specific revision being procured.

Selection Notes

Select this component when dual-channel high-side switching is required for USB-compliant loads. The 400mΩ on-resistance offers a balance between conduction loss and cost. Consider the 150mA continuous current rating against peak load demands. The MSOP package is suitable for space-constrained designs requiring thermal performance within the specified industrial temperature range.

Part Context

The MIC2536 series consists of cost-effective high-side power switches designed for USB applications. The MIC2536-2BMM specifically denotes the dual-channel variant in an MSOP-8 package. This part integrates intelligent power control features to protect downstream loads from overcurrent and thermal faults while maintaining compliance with USB specifications.

Replacement Considerations

Cross-reference with MIC2536-2BM or MIC2536-2BMM-TR for identical functional specifications. Verify pinout compatibility and package dimensions before substitution. Ensure the substitute part maintains the same voltage and current ratings.
