MIC94093YMT-TR

Overview

The MIC94093YMT-TR is a high-side load switch manufactured by Microchip Technology, designed for power distribution applications. It features a single output capable of delivering up to 1.2A of continuous current. The device operates within an input voltage range of 1.7V to 5.5V and exhibits a maximum on-resistance of 225 mOhms. Key timing parameters include a maximum turn-on time of 1.5 ms and a maximum turn-off time of 200 ns. It is housed in a 4-pin MLF package and supports surface mount installation. The component functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates controlled slew rate management to mitigate inrush currents during switching events.
• Includes internal load discharge circuitry to safely dissipate stored energy when the switch is off.
• Utilizes non-inverting logic control interface for straightforward system integration.

Applications

• USB port protection and power sequencing
• Battery-powered portable electronic devices
• General-purpose high-side load switching in embedded systems

Procurement Notes

Verify the specific suffix YMT against official Microchip documentation to confirm the 4-TMLF package configuration. Ensure compatibility with moisture sensitivity levels (MSL) requirements for your assembly process. Cross-reference the lead times provided by authorized distributors, as supply chain variability may impact delivery schedules. Confirm that the reel or cut-tape packaging aligns with your pick-and-place equipment specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact high-side switch with integrated load discharge is required for low-voltage systems. The 1.2A current rating suits moderate load applications where space constraints necessitate a small footprint. Consider the 1.7V minimum operating voltage to ensure compatibility with your system's rail. The controlled slew rate feature makes it suitable for sensitive loads requiring soft-start capabilities without external components.

Part Context

This part belongs to the MIC94093 family of power switches from Microchip Technology. The family includes variants with different packages, such as the SC-70-6 version (MIC94093YC6-TR). These devices are categorized under USB load switches and power distribution ICs, targeting applications requiring efficient power management in consumer electronics and industrial controls.

Replacement Considerations

The MIC94093YC6-TR serves as a functional alternative within the same series, offering identical electrical performance but utilizing a 6-pin SC-70-6 package instead of the 4-pin MLF. Designers must verify pinout compatibility and PCB footprint changes if substituting between these package types.
