MIC2562A-1YTS-TR

Overview

The MIC2562A-1YTS-TR is a PCMCIA/Cardbus socket power controller manufactured by Microchip Technology. It features a 3:2 input-to-output ratio with two N-channel low-side switches, each capable of delivering up to 200mA. The device operates without an external supply voltage and supports load voltages of 3.3V, 5V, and 12V. It includes fixed current limiting and overtemperature protection, along with status flag outputs. The component is housed in a 16-TSSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual N-channel low-side switches for independent channel control
• Provides integrated fault protection including fixed current limiting and thermal shutdown
• Outputs status flags to indicate operational state or fault conditions
• Operates directly from system logic levels without requiring auxiliary power

Applications

• PCMCIA card socket power management
• Cardbus interface power distribution
• Portable computing device power switching

Procurement Notes

Verify the specific suffix '1YTS' to confirm the 16-TSSOP package variant, as other suffixes denote different packages like SOIC. Confirm RoHS compliance status via the latest datasheet revision. Check for obsolete status notifications, as this family has undergone lifecycle changes. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when designing systems requiring dedicated power control for PCMCIA or Cardbus slots. It is suitable for applications needing isolated switch control with built-in fault protection. Consider the 16-TSSOP footprint constraints. Verify that the 200mA per channel output current meets the load requirements. Ensure compatibility with the target logic voltage levels for proper switching operation.

Part Context

This part belongs to the MIC2562 series of power switches designed specifically for PCMCIA and Cardbus applications. It simplifies power sequencing and protection compared to discrete solutions. The series offers various package options to accommodate different board space requirements while maintaining consistent electrical performance characteristics across variants.
