MIC2564A-0YTS

Overview

The MIC2564A-0YTS is a dual serial PCMCIA/CardBus power controller manufactured by Microchip Technology. It functions as a sophisticated power switching matrix designed to control VCC and VPP voltages for two PC Card slots. The device integrates four N-channel high-side switches with a 3:4 input-to-output ratio, managed via a serial interface. It operates within a load voltage range of 3.3V, 5V, and 12V. The component features fixed current limiting and overtemperature fault protection mechanisms. It is housed in a 24-TSSOP surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

Dual serial control architecture for managing power distribution across two PC Card slots
Integrated N-channel high-side switches with fixed current limiting and overtemperature protection
Serial data interface for precise configuration and status monitoring of power states

Applications

PCMCIA card slot power management systems
CardBus peripheral power distribution controllers
Laptop and mobile computing device power switching matrices

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to obsolete status. Confirm RoHS compliance and REACH status prior to integration. Validate that the 24-TSSOP footprint matches PCB design requirements. Ensure supply chain sources provide valid traceability documentation for legacy components.

Selection Notes

Select this component for applications requiring independent control of VCC and VPP rails for dual PCMCIA slots. The serial interface reduces pin count compared to parallel alternatives. Consider the 120mA output capability per switch when sizing loads. Verify compatibility with existing serial control logic levels and timing constraints.

Part Context

This part belongs to the MIC2564 family of power distribution switches. It serves as a specialized solution for portable computing hardware requiring robust power sequencing and protection. The device replaces discrete transistor arrays with an integrated controlled switching matrix.
