MIC2090-2YM5-TR

Overview

The MIC2090-2YM5-TR is a single-channel, high-side power distribution switch manufactured by Microchip Technology. It utilizes a P-channel MOSFET architecture to manage load power within a voltage range of 1.8V to 5.5V. The device provides a maximum output current of 100mA and features an on-resistance of 1.2 ohms maximum. It incorporates latch-off current limiting protection to safeguard against overcurrent conditions. The component operates reliably across a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Integrates high-side P-channel switching for direct load control
• Provides latch-off current limiting protection against fault conditions
• Includes status flag output for monitoring operational state
• Operates without external supply voltage requirements

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing overcurrent protection
• Embedded circuits with limited space constraints
• Peripheral power distribution in consumer electronics

Procurement Notes

Verify the specific suffix YM5 corresponds to the required SOT-23-5 packaging variant when sourcing. Confirm RoHS3 compliance status aligns with project environmental regulations. Ensure the latch-off behavior matches system recovery requirements, as this differs from auto-restart variants. Cross-reference the manufacturer part number with official Microchip documentation to avoid confusion with similar MIC2091 models that feature different protection logic.

Selection Notes

Select this component when a simple, cost-effective high-side switch with robust fault protection is required. The latch-off feature necessitates manual reset after a fault, which suits applications where immediate re-engagement is unsafe. Compare against MIC2091 if automatic recovery after fault clearance is preferred. Ensure the load current does not exceed the 100mA limit and that the voltage range fits the 1.8V to 5.5V specification.

Part Context

This part belongs to the MIC209x family of power switches designed for portable applications. It shares the same physical footprint and basic switching characteristics with the MIC2091 series but differs in its fault response mechanism. While the MIC2091 offers auto-restart, the MIC2090 employs a latch-off strategy, providing distinct safety profiles for different system designs.

Replacement Considerations

MIC2091-2YM5-TR serves as a functional alternative if auto-restart capability is acceptable instead of latch-off. Verify pin compatibility and electrical parameters before substitution.
