Overview
The MIC2563A-0BSM TR is a dual-slot PCMCIA/CardBus power controller manufactured by Microchip Technology. It integrates high-efficiency N-channel switches to manage VCC and VPP rails for two PC Card slots within a single package. The device supports input voltages of 3.3V, 5V, and 12V, delivering up to 1A on VCC outputs and 250mA on VPP outputs. It features a 28-pin SSOP package and operates across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates complete switch matrix for dual PC Card/CardBus slots in one package
- High-efficiency self-biased N-channel switches require no external 12V bias supply
- Includes output current limiting and over-temperature shutdown protection
- Ultra-low standby current consumption for extended battery life
Applications
- Dual-slot PC Card and CardBus socket power control
- Data collection systems requiring portable storage interfaces
- Machine control data input systems with PCMCIA connectivity
- Barcode data collection devices
Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration when sourcing. Confirm that the component matches the 28-SSOP physical footprint and lead finish specifications required by your assembly process. Ensure compatibility with standard PC Card logic controllers for proper interface signaling.
Selection Notes
Select this component for designs requiring independent control of two PC Card slots without external discrete switching components. It is suitable for applications needing low standby current and robust protection against cross-conduction or thermal events. Verify that the system logic levels align with the controller's digital inputs for accurate voltage selection.
Part Context
This part belongs to the MIC2563 family of power management ICs designed specifically for PCMCIA and CardBus standards. It serves as an integrated solution for managing complex power sequencing and distribution in portable computing devices, replacing multiple discrete transistors and drivers with a single controlled unit.
Replacement Considerations
MIC2563A-0BSM is an improved version of the MIC2563 offering lower on-resistance and additional VCC pull-down clamping in shutdown mode. Direct pin-compatible substitutes should be verified against official Microchip documentation for equivalent electrical characteristics and package dimensions.
