MIC2562A-1YM-TR

Overview

The MIC2562A-1YM-TR is a PCMCIA/CardBus socket power controller manufactured by Microchip Technology. It features two N-channel outputs with a 3:2 input-to-output ratio, designed for low-side switching applications. The device supports load voltages of 3.3V, 5V, and 12V without requiring a separate supply voltage. Key electrical specifications include a maximum output current of 200mA per channel and a typical on-resistance of 70mΩ. It incorporates fixed current limiting and overtemperature fault protection, along with status flag indicators. The component operates within a temperature range of -40°C to +85°C and is housed in a 14-SOIC package.

Feature Summary

• Integrates dual N-channel power switches with a 3:2 control ratio for PCMCIA and CardBus sockets
• Provides comprehensive fault protection including fixed current limiting and thermal shutdown
• Features logic interface inputs with non-inverted control and status flag outputs
• Operates directly from system loads (3.3V, 5V, 12V) without external supply requirements

Applications

• PCMCIA socket power management
• CardBus socket power distribution
• High-side switch control circuits
• Load driver applications

Procurement Notes

Verify the specific suffix '1YM' against the official Microchip datasheet to confirm pinout and functional compatibility. Note that this component may be subject to lifecycle restrictions; check current availability status as it might be classified as Not Recommended for New Designs. Ensure the 14-SOIC package dimensions match your PCB footprint requirements before procurement.

Selection Notes

Select this component when designing power systems for PCMCIA or CardBus interfaces requiring integrated fault protection. The 70mΩ on-resistance and 200mA current rating suit moderate load applications. Consider the lack of an independent VCC requirement if space constraints prevent adding auxiliary power rails. Verify that the low-side output configuration aligns with the target circuit topology.

Part Context

This part belongs to the MIC2562A series of power controllers specifically engineered for portable computing standards. It consolidates multiple discrete switching and protection components into a single IC, reducing board space and complexity. The series is tailored for legacy expansion slots, providing reliable power sequencing and monitoring capabilities essential for compliant hardware design.
