MIC2563A-1YSM

Overview

The MIC2563A-1YSM is a dual-slot PCMCIA/CardBus socket power controller designed to manage VCC and VPP voltage switching. It supports VCC outputs of 0V, 3.3V, or 5.0V and VPP outputs of OFF, 0V, 3.3V, 5V, or 12.0V, selected via digital inputs. The device provides up to 1A for VCC and 250mA for VPP currents. Operating from a 3V to 14.5V supply, it features self-biasing for 3.3V/5V outputs without requiring a +12V bias. Key electrical protections include current limiting, overtemperature shutdown, and shoot-through lockout. It operates within a -40°C to +85°C temperature range.

Feature Summary

• Integrates complete dual-slot power switching matrix for PC Card and CardBus sockets in a single package.
• Self-biased high-current VCC and medium-current VPP switches eliminate the need for external 12V bias supplies.
• Ensures stable power transitions with shoot-through lockout and controlled rise/fall times.
• Includes comprehensive protection mechanisms such as output current limiting and thermal shutdown.

Applications

• Dual-slot PCMCIA and CardBus socket power management
• Data collection systems and machine control data input
• Barcode data collection devices

Procurement Notes

Verify the specific suffix '1YSM' against the manufacturer's official datasheet to confirm pinout compatibility and environmental compliance status. Ensure the ordering code matches the required tape-and-reel or tube packaging format. Cross-reference the revision level to guarantee alignment with current design specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated control for two PCMCIA/CardBus slots. It is suitable for applications needing precise VCC and VPP voltage sequencing without external bias generation. Consider its low standby current for battery-operated devices. Verify that the 28-pin SSOP package fits the board layout constraints and that the operating temperature range meets the system requirements.

Part Context

This part belongs to the MIC2563 family of power controllers. The MIC2563A variant offers improved performance over the original MIC2563, including lower on-resistance and VCC pull-down clamping in shutdown mode. It serves as a specialized interface between system logic and PC card sockets, replacing discrete switching solutions with a consolidated IC approach.

Replacement Considerations

The MIC2563A is an enhanced version of the MIC2563. Check if the original MIC2563 is available as a direct substitute, noting differences in on-resistance and shutdown behavior. Ensure any replacement maintains the 28-pin SSOP footprint and compatible logic levels for seamless integration into existing designs.
