Overview
The MIC2568-0BSM is a dual-slot PC Card/CardBus power controller manufactured by Microchip Technology. It functions as a VCC and VPP power switch matrix designed to support 3.3V and 5V PC Card (PCMCIA) slot power supply pins. The device integrates an N-channel power switch driver with a maximum continuous current rating of 120mA per channel. It operates within a supply voltage range of 3.3V to 5V and features an operating temperature range from -40°C to +85°C. The component is housed in a 28-pin SSOP package.
Feature Summary
- Supports dual-slot PC Card and CardBus power control architectures
- Integrates individual switching capability for VCC and VPP outputs between 0V and supply levels
- Includes integrated charge pump functionality for efficient power management
Applications
- Dual-slot PC Card power management systems
- CardBus interface power distribution
- PCMCIA slot power supply control
Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required packaging options, such as tape and reel configurations. Confirm that the component meets RoHS compliance standards if environmental regulations apply to the target assembly. Cross-reference the exact part number against official Microchip documentation to validate current availability status, as this series may have discontinued variants or updated revisions.
Selection Notes
Select this component when designing systems requiring independent control of VCC and VPP rails for dual-slot PC Card interfaces. Ensure the application demands a maximum continuous current of 120mA per channel. Verify that the operational environment falls within the specified -40°C to +85°C temperature range. Consider the 28-SSOP package constraints during PCB layout planning.
Part Context
The MIC2568 series serves as a specialized power controller for legacy computing interfaces. This specific model addresses the power sequencing and distribution needs for dual-slot configurations. It consolidates multiple switching functions into a single integrated circuit, reducing board space compared to discrete solutions. The design focuses on reliability for PCMCIA and CardBus applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official Microchip channels for potential obsolescence management or direct replacements.
