MIC94095YMT-TR

Overview

The MIC94095YMT-TR is a high-side power switch manufactured by Microchip Technology. It features a single output capable of delivering up to 1.2A of load current with a maximum on-state resistance of 0.13Ω. The device operates within an input voltage range of 1.7V to 5.5V and supports a high-true enable logic level. It is housed in a compact 4-pin TDFN (TMLF) package with an exposed pad, designed for surface-mount applications. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• High-side load switching capability with low on-resistance for efficient power distribution
• Compact 4-pin TDFN package design suitable for space-constrained PCB layouts
• Wide operating voltage range supporting standard 1.8V, 3.3V, and 5V systems
• Extended industrial temperature rating for reliable operation in harsh environments

Applications

• USB port protection and power management
• Peripheral power sequencing in embedded systems
• Battery-powered device load switching
• Industrial control board power distribution

Procurement Notes

Verify the specific datasheet revision and package marking code upon receipt to ensure authenticity. Confirm that the exposed thermal pad soldering process meets the manufacturer's recommended land pattern guidelines for optimal thermal performance. Check for moisture sensitivity level compliance during storage and handling to prevent package damage before reflow soldering.

Selection Notes

Select this component when a low-profile, high-current high-side switch is required for 5.5V systems. The 0.13Ω on-resistance minimizes power dissipation compared to higher-resistance alternatives. Ensure the application requires a single-channel configuration and can accommodate the 4-pin TDFN footprint. Verify that the enable signal polarity matches the high-true logic requirement of the device.

Part Context

This part belongs to the MIC9409x series of high-side load switches from Microchip Technology. The series offers various configurations with different on-resistances and current ratings. The MIC94095 variant specifically targets applications requiring lower conduction losses while maintaining a small form factor. It complements other components in power management IC portfolios for complete system solutions.

Replacement Considerations

Cross-reference with MIC94093YMT-TR or MIC94091YMT-TR for similar functionality with different on-resistance values. Verify pinout compatibility and thermal characteristics before substitution. Ensure the alternative part meets the same voltage and current specifications for the target application.
