MIC2505-1YM-TR

Overview

The MIC2505-1YM-TR is a fully integrated high-side power switch manufactured by Microchip Technology. It features a single N-channel output capable of handling up to 2A of continuous current. The device operates within a supply voltage range of 3V to 7.5V and includes a maximum on-resistance of 50mΩ. Key protection mechanisms include fixed current limiting, overtemperature shutdown, and under-voltage lockout (UVLO). It is housed in an 8-pin SOIC package and supports surface-mount installation across an operating temperature range of -40°C to +85°C.

Feature Summary

• Fully integrated high-side switch with single channel output
• Built-in fault protection including current limit and thermal shutdown
• Low on-resistance for efficient power distribution
• Under-voltage lockout prevents operation below safe thresholds

Applications

• Power distribution in portable electronic devices
• Load switching in industrial control systems
• Peripheral power management in consumer electronics
• Battery-powered equipment load protection

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements as stated in the manufacturer's datasheet. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Ensure the selected variant matches the required lead-free status for assembly processes.

Selection Notes

Select this component when a single-channel high-side switch with 2A capacity is required. Consider the 50mΩ on-resistance for efficiency calculations. Verify that the 3V to 7.5V input range aligns with the system power supply. Ensure the 8-SOIC package fits the PCB layout constraints. Check if the integrated protection features meet the safety requirements of the target application without needing external circuitry.

Part Context

The MIC2505 series belongs to Microchip's family of high-side switches designed for power distribution applications. This specific model represents the single-channel variant with a 2A rating. It is often compared with dual-channel versions like the MIC2506 or lower-current variants within the same product line. The device serves as a compact solution for managing loads in space-constrained designs requiring integrated protection.

Replacement Considerations

Direct substitutes may include other single-channel high-side switches from Microchip with similar current ratings and pin configurations. Verify compatibility regarding voltage ranges, package dimensions, and protection feature sets before substitution.
