Overview
The MIC2074-2YM-TR is a dual high-side power distribution switch manufactured by Microchip Technology. It provides independent control of two loads with integrated circuit protection features. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of up to 500 mA per channel. Key specifications include a typical on-resistance (Rds On) of 115 mΩ, fixed current limiting, and thermal shutdown. It is housed in a 16-pin SOIC package and is designed for surface-mount installation.
Feature Summary
- Dual-channel high-side switching capability with independent load control
- Integrated fault protection including fixed current limit and thermal shutdown
- Controlled slew rate to minimize inrush current during turn-on
- Status flag output for monitoring switch state and fault conditions
Applications
- General-purpose power distribution in embedded systems
- Hot-swap applications requiring controlled power sequencing
- Peripheral power management in industrial equipment
- USB port power switching and protection circuits
Procurement Notes
Verify component authenticity through authorized Microchip distributors. Confirm package marking and date codes against official datasheets. Check for RoHS compliance status as manufacturing processes may evolve. Ensure storage conditions meet moisture sensitivity level requirements prior to reflow soldering.
Selection Notes
Select this component when dual-channel high-side switching with integrated protection is required. Consider the 115 mΩ on-resistance for power loss calculations. Evaluate the 500 mA current limit against peak load requirements. Verify compatibility with system logic levels for the non-inverting input interface.
Part Context
This part belongs to the MIC207x series of USB power switches from Microchip Technology. It shares architectural similarities with the MIC2073 and MIC2075 models but offers dual-channel functionality. The series is optimized for general-purpose power distribution with enhanced circuit protection capabilities compared to basic MOSFET solutions.
Replacement Considerations
Public documentation indicates the MIC2074-2YM-TR is obsolete and no longer manufactured. Engineers should consult Microchip for recommended replacement parts or design updates. Alternative solutions may require external protection components if direct pin-to-pin substitutes are unavailable.
