MIC2074-1YM

Overview

The MIC2074-1YM is a dual-channel high-side power switch IC from Microchip Technology, designed for portable electronics and USB applications. It features an N-channel output configuration with a maximum continuous current of 500mA per channel. The device operates within a load voltage range of 2.7V to 5.5V and utilizes an 8-SOIC surface-mount package. Key electrical characteristics include a typical on-resistance of 90 milliohms and a fixed current limit protection mechanism. It integrates comprehensive fault protection including over-temperature, under-voltage lockout (UVLO), and thermal shutdown, ensuring reliable operation in space-constrained designs.

Feature Summary

• Dual-channel high-side power switching capability for independent load control
• Integrated fixed current limit and thermal protection for robust fault management
• Controlled slew rate functionality to minimize inrush current and EMI
• Status flag output for real-time monitoring of switch conditions

Applications

• Portable consumer electronics power distribution
• USB peripheral hub power switching
• IoT device load management
• Wearable technology power rails

Procurement Notes

Verify the specific manufacturer part number against official Microchip databases, as availability may vary due to lifecycle status changes. Confirm that the 8-SOIC package dimensions and pinout match the target PCB footprint requirements. Ensure compliance with RoHS3 specifications if required by the end-product regulations. Cross-reference the datasheet revision history to confirm the active status of the component before finalizing procurement plans.

Selection Notes

Select this component when dual-channel high-side switching is required within a 2.7V to 5.5V system voltage range. The 500mA per channel rating suits low-power loads such as sensors or small peripherals. Consider the 8-SOIC package for surface-mount assembly constraints. Evaluate the fixed current limit threshold against the maximum expected load current to ensure adequate protection margins without nuisance tripping during normal operation.

Part Context

The MIC2074-1YM belongs to the MIC207x series of power distribution switches from Microchip Technology. This series is optimized for low-voltage, low-power applications where space efficiency and integrated protection are critical. It complements other variants like the MIC2075 and MIC2076, which offer single or different channel configurations, providing designers with scalable solutions for various power distribution needs in compact electronic devices.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The MIC2074-1YM is listed as obsolete in some distributor records; verify current manufacturing status directly with Microchip Technology. If replacement is necessary, consult the official datasheet for functional equivalents within the same product family or contact the manufacturer for recommended alternatives.
