Overview
The MIC2566-0YM is a power distribution switch IC manufactured by Microchip Technology, designed for low-voltage applications such as PCMCIA and Card Bus sockets. It features two independent outputs with a maximum on-resistance of 1.4 Ohms and supports load voltages of 3.3V and 5V. The device provides an output current capacity of 120 mA per channel. Key timing specifications include a maximum off time of 1 microsecond and a maximum on time of 50 microseconds. It is housed in a 14-SOP package.
Feature Summary
- Dual-channel power switching capability for independent load control
- Optimized for low-voltage PCMCIA and Card Bus socket applications
- Fast switching performance with microsecond-level timing characteristics
Applications
- PCMCIA socket power management
- Card Bus socket power distribution
- Low-voltage peripheral power switching
Procurement Notes
Verify the specific suffix '0YM' against the manufacturer's official datasheet to confirm pinout and electrical parameters. Ensure the component is RoHS compliant if required by your assembly process. Cross-reference the 14-SOP package dimensions with your PCB footprint design to guarantee mechanical compatibility during procurement.
Selection Notes
Select this component when dual-channel power switching is required for legacy PCMCIA or Card Bus interfaces. The 1.4 Ohm on-resistance and 120 mA current rating suit low-power peripheral loads. Consider the 14-SOP package size and the specific on/off timing requirements relative to system startup sequences before finalizing the design.
Part Context
This part belongs to the MIC2566 series of power distribution switches from Microchip Technology. These ICs are specialized for managing power in portable computing environments, specifically targeting standards like PCMCIA and Card Bus. The series focuses on reliable power delivery for memory and I/O cards in laptops and embedded systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with any potential alternatives by comparing the 14-SOP package, 120 mA current rating, and 1.4 Ohm on-resistance specifications directly with the original datasheet.
