MIC2562-OBM

Overview

The MIC2562-0BM is a PCMCIA Cardbus power switch controller manufactured by Microchip Technology, housed in a 14-SOIC package. It features two N-channel low-side outputs with a typical on-resistance of 70 milliohms and a maximum output current of 200mA per channel. The device supports load voltages of 3.3V, 5V, and 12V with a 3:2 input-to-output ratio. It includes fixed current limiting and thermal shutdown protection, operating within a temperature range of -40°C to +85°C.

Feature Summary

• Provides integrated control for PCMCIA Cardbus power sequencing
• Includes status flag output for fault monitoring
• Features built-in overcurrent and overtemperature protection

Applications

• PCMCIA Cardbus slot power management
• Laptop computer peripheral power distribution
• Portable electronic device hot-swap interfaces

Procurement Notes

Verify the specific suffix '0BM' against official Microchip documentation to confirm pinout and electrical specifications. Ensure the component matches the 14-SOIC package dimensions. Confirm that the manufacturer designation aligns with Microchip Technology, as Micrel was acquired. Request datasheets directly from authorized distributors to validate revision levels and RoHS compliance status before integration into designs.

Selection Notes

Select this controller when designing systems requiring dedicated power sequencing for Cardbus interfaces. It is suitable for applications needing low on-resistance switches with integrated protection. Consider the 14-SOIC footprint for board space constraints. Verify compatibility with system logic levels and required load voltage ranges of 3.3V, 5V, or 12V during the design phase.
