Overview
The MIC2563A-1BSM TR is a dual-slot PCMCIA/CardBus power controller manufactured by Microchip Technology in a 28-pin SSOP package. It manages VCC and VPP voltage switching for two slots, supporting VCC levels of 0V, 3.3V, and 5.0V, and VPP levels of OFF, 0V, 3.3V, 5V, or 12.0V. The device provides up to 1A output current for VCC and 250mA for VPP. It operates with a typical standby current of 0.3µA and includes fixed current limiting and over-temperature shutdown protection.
Feature Summary
- Integrates complete dual-slot power switching matrix within a single package to reduce board space.
- Utilizes self-biased switches that eliminate the need for external +12V bias supplies.
- Ensures stable power transitions through break-before-make switching logic without voltage shoot-through.
- Provides comprehensive protection via output current limiting and thermal shutdown mechanisms.
Applications
- Dual-slot PC Card and CardBus power supply control
- Data collection systems requiring portable storage interfaces
- Machine control data input systems
Procurement Notes
Verify the specific suffix '1BSM' against the manufacturer's official datasheet to confirm pinout compatibility and environmental compliance status. Ensure the ordering code matches the required tape-and-reel configuration for automated assembly processes. Cross-reference the revision level to guarantee alignment with system design specifications.
Selection Notes
Select this component when designing systems requiring independent control of two PCMCIA/CardBus slots. It is suitable for applications needing low standby current to preserve battery life. Choose this part if the design requires integrated protection features without external discrete components. Verify that the 28-pin SSOP package fits the available PCB footprint constraints.
Part Context
This component belongs to the MIC2563 family of power controllers designed specifically for PCMCIA and CardBus standards. It serves as an enhanced version of previous models, offering improved on-resistance and additional clamping features. The device simplifies power management by integrating multiple switching functions into a compact surface-mount package.
Replacement Considerations
The MIC2563A is an improved version of the MIC2563. Verify functional equivalence before substituting older revisions. No direct public substitute part numbers are confirmed in the provided documentation.
