MIC2099-1YMT-TR

Overview

The MIC2099-1YMT-TR is a high-side power distribution switch manufactured by Microchip Technology. It features a single P-channel output configured for high-side switching applications. The device supports load voltages ranging from 2.5V to 5.5V and provides a programmable current limit adjustable between 0.1A and 1.1A. Housed in a compact 6-pin TDFN EP package with dimensions of 1.60 x 1.60 mm, it utilizes an On/Off interface for control. This component is designed for efficient power management in space-constrained electronic systems.

Feature Summary

• High-side switching architecture utilizing a P-channel output configuration
• Programmable current limiting capability for precise load protection
• Compact 6-pin TDFN EP package design suitable for space-constrained PCB layouts

Applications

• Power distribution switches in portable consumer electronics
• Load driver circuits requiring high-side control
• USB hub power management systems

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel packaging configuration. Confirm that the 6-pin TDFN EP footprint aligns with the target PCB design constraints. Ensure the voltage rating of 5.5V maximum is sufficient for the intended application environment. Cross-reference the manufacturer's latest datasheet to confirm active status and compliance with RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when a high-side switch with adjustable current limiting is required for low-voltage DC loads. The programmable current limit allows customization for different load profiles without external sensing resistors. The small form factor makes it ideal for dense circuit boards where space is limited. Consider the 2.5V to 5.5V operating range to ensure compatibility with the system's power supply rails.

Part Context

This part belongs to the MIC2099 series of current-limiting power distribution switches. It serves as a robust solution for protecting downstream components from overcurrent conditions. The series offers various package options, but this specific model focuses on the compact TDFN format. It complements other power management ICs within the Microchip portfolio for complete system power solutions.

Replacement Considerations

Direct substitutes include the MIC2099-1YMT variant, which shares identical electrical characteristics and pinout configurations. Verify that any replacement maintains the same 6-pin TDFN EP package dimensions. Ensure the replacement part supports the same 2.5V to 5.5V voltage range and programmable current limit specifications.
