MIC2564A-1BSM

Overview

The MIC2564A-1BSM is a sophisticated power switching matrix designed for PC Card and CardBus applications. It controls VCC and VPP voltages to two PC Card slots using a serial interface. The device features status flags and non-inverting input types with N-channel output switches. Packaged in a 24-SSOP format, it integrates load switch capabilities with reverse current protection. Operating from a single supply, it manages power sequencing and monitoring for portable computing systems requiring reliable slot voltage regulation.

Feature Summary

• Controls VCC and VPP voltages for dual PC Card slots
• Integrates serial data interface for command control
• Provides status flag reporting for system monitoring
• Includes reverse current protection functionality

Applications

• PCMCIA card slot power management
• CardBus slot voltage regulation
• Portable computer power sequencing
• Embedded system slot controllers

Procurement Notes

Verify the manufacturer marking matches Microchip Technology or Micrel legacy branding. Confirm the 24-SSOP package dimensions align with specifications. Ensure the part number suffix indicates the correct variant. Request original datasheets to validate electrical characteristics against application requirements before procurement.

Selection Notes

Select this component when managing dual PC Card slots requiring precise VCC and VPP control. The serial interface reduces pin count compared to parallel alternatives. Consider the 24-SSOP package for space-constrained designs. Verify compatibility with existing system logic levels and power sequencing requirements.

Part Context

This part belongs to the MIC2564 series of power management ICs. It is often associated with legacy Micrel Semiconductor products now under Microchip Technology. The series targets portable electronics needing robust slot power control. Similar parts may include variants with different package options or feature sets.

Replacement Considerations

Check for SGM2564A as a potential alternative from SG Micro. Verify pinout compatibility and electrical specifications match. Ensure the substitute supports dual slot control if required. Confirm package availability and lead times for production needs.
