Overview
The MIC2562A-1BM is a PCMCIA power controller manufactured by Microchip Technology. It features two N-channel low-side outputs with a 3:2 input-to-output ratio, designed for 3.3V, 5V, and 12V load voltages. Key electrical parameters include a maximum on-time of 250 µs and off-time of 1 µs. The device operates within a temperature range of -40°C to +85°C and utilizes a 14-SOIC surface-mount package.
Feature Summary
- Integrates logic interface for direct control of PC Card slot power supply pins
- Provides fixed current limiting and overtemperature fault protection mechanisms
- Supports switching between multiple VCC and VPP voltage levels required by PC Cards
Applications
- PCMCIA card slot power management
- CardBus power controller implementation
- Portable computer peripheral power distribution
Procurement Notes
Verify the specific suffix '1BM' against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure the ordering information matches the exact package type and operating temperature range required for your design. Cross-reference with authorized distributors to validate part authenticity and avoid counterfeit components.
Selection Notes
Select this component when designing systems requiring dedicated power sequencing for PCMCIA or CardBus interfaces. It is suitable for applications needing integrated fault protection and multi-voltage support without external discrete logic. Consider the 14-SOIC package constraints and thermal dissipation requirements during PCB layout planning.
Part Context
This part belongs to the MIC2562 series of power distribution switches. It is specifically engineered for Personal Computer Memory Card International Association (PCMCIA) standards. The device simplifies power management by integrating necessary switching and protection functions into a single IC, reducing board space and component count in portable electronic devices.
Replacement Considerations
Consult official substitution lists for compatible alternatives. Verify that any replacement maintains the same 3:2 ratio, SOIC package, and voltage ratings.
