MIC2562A-0BM

Overview

The MIC2562A-0BM is a power switch controller designed for PCMCIA and Cardbus applications. It features two N-channel outputs with a 3:2 input-to-output ratio, supporting load voltages of 3.3V, 5V, and 12V. The device delivers a maximum output current of 200mA with a typical on-resistance of 70 milliohms. It operates without a separate Vcc/Vdd supply and includes status flag features. Protection mechanisms include fixed current limiting and overtemperature shutdown. The component functions within an ambient temperature range of -40°C to 85°C and is housed in a 14-SOIC package.

Feature Summary

• Integrates dual N-channel power switches for PCMCIA and Cardbus socket power control
• Provides fixed current limiting and overtemperature fault protection
• Includes status flag indication for operational monitoring
• Operates directly from system logic inputs without auxiliary power supply

Applications

• PCMCIA socket power management
• Cardbus socket power distribution
• System voltage switching for VCC and VPP rails

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 14-SOIC configuration. Confirm that the sourcing channel provides genuine components with traceable manufacturing dates. Cross-reference the part number with the latest datasheet revisions to validate electrical parameters and pinout assignments before integration into design schematics.

Selection Notes

Select this component when designing systems requiring dedicated power switching for PCMCIA or Cardbus interfaces. The integrated logic interface simplifies control by eliminating the need for external driver circuits. Consider the 70 milliohm on-resistance for efficiency calculations in low-voltage applications. The absence of a separate supply voltage requirement reduces bill-of-materials complexity. Evaluate the thermal performance relative to the expected load current and ambient operating conditions.

Part Context

The MIC2562A-0BM belongs to the MIC2562 family of power controllers manufactured by Microchip Technology. This series is specifically engineered for portable computing applications involving expansion slots. The device consolidates multiple power switching functions into a single integrated circuit, replacing discrete MOSFET arrangements. It supports standard voltage levels required by legacy and modern expansion card standards.
