MIC2505-2BN

Overview

The MIC2505-2BN is a single-channel, high-side power switch manufactured by Microchip Technology. It utilizes an N-channel MOSFET architecture to manage load connections with a fixed current limit of 2A. The device operates within a supply voltage range of 3V to 7.5V and features a maximum on-resistance of 50mΩ. Key electrical parameters include a turn-on time of 2ms and an idle time of 20μs. It provides comprehensive fault protection mechanisms including over-temperature shutdown, under-voltage lockout (UVLO), and fixed current limiting. The component is housed in an 8-pin PDIP package.

Feature Summary

• Integrates slew rate control to minimize inrush current and electromagnetic interference during switching events
• Includes a status flag output to indicate active fault conditions or normal operation states
• Provides robust fault protection against over-temperature conditions and under-voltage lockout scenarios

Applications

• Peripheral power management for USB-connected devices
• Hot-swappable circuit interfaces requiring controlled turn-on characteristics
• Battery-powered systems needing efficient high-side load switching

Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. Ensure the procurement source provides valid datasheets confirming the 8-pin DIP configuration. Cross-reference the manufacturer part number with official Microchip documentation to avoid counterfeit components. Confirm that the received units match the specified electrical characteristics for high-side switching applications.

Selection Notes

Select this component when a single-channel high-side switch with integrated fault protection is required. Consider the 2A current limit and 50mΩ on-resistance for load compatibility. Evaluate the need for slew rate control to protect sensitive downstream loads. Verify that the operating voltage range aligns with the system's power supply rails. Assess thermal requirements based on the expected load current and ambient conditions.

Part Context

The MIC2505 series comprises high-side switches designed for power distribution applications. The MIC2505-2BN specifically represents the single-channel variant with a 2A capacity. It belongs to a family that includes dual-channel options and different packaging styles. This component addresses the need for reliable load switching with built-in diagnostic capabilities in compact form factors.

Replacement Considerations

Direct substitutes may include other single-channel high-side switches from Microchip with similar current ratings. Verify pin compatibility and electrical specifications before substitution. Alternative packages such as SOIC variants exist within the same product family.
