Procurement Notes
Verify the specific suffix '0YSM' against the manufacturer's official datasheet to confirm pinout and electrical characteristics, as variations exist within the MIC2564 family. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for obsolescence notices or recommended replacement parts from Microchip Technology before finalizing procurement plans.
Selection Notes
Select this component when designing systems requiring independent control of VCC and VPP rails for multiple PC Card slots. Ensure the design supports the required serial communication protocol. Verify that the load current does not exceed the internal fixed limit. Consider the thermal performance in the 24-SSOP package under maximum load conditions.
Part Context
This part belongs to the MIC2564 series of power switching matrices. It is specifically engineered for portable computing environments where space-constrained power distribution is critical. The series offers integrated protection features to safeguard connected peripherals from electrical faults.
Replacement Considerations
Public confirmed substitute: TPS2224ADB (Texas Instruments). Verify compatibility regarding pinout, voltage ratings, and control logic before substitution.
