MIC2342-2YTQ-TR

Hot Swap Controllers Overview

The MIC2342-2YTQ-TR is a hot plug controller designed for PCI Express applications, manufactured by Microchip Technology. It operates within a maximum power supply voltage of 3.6 V and supports six channels. The device features automatic retry capabilities, thermal limiting, and under-voltage lockout (UVLO) to ensure system stability during insertion or removal events. It is housed in a TQFP-48 package measuring 7x7 mm and is rated for an operating temperature range from 0°C to 70°C. The component utilizes surface mount technology and is supplied in tape and reel packaging.

Hot Swap Controllers Feature Summary

• Integrated thermal limiting protection to manage heat dissipation during hot plug operations
• Automatic retry functionality to handle transient faults without manual intervention
• Under-voltage lockout mechanism ensures stable operation within specified voltage thresholds

Hot Swap Controllers Applications

• PCI Express hot swap control systems
• Server backplane power management
• Industrial I/O card insertion interfaces

Hot Swap Controllers Procurement Notes

Verify the exact suffix against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with the target PCB footprint for the TQFP-48 housing. Confirm that the intended application environment falls within the specified 0°C to 70°C operating temperature range. Check for RoHS compliance status if required by specific regulatory standards.

Hot Swap Controllers Selection Notes

Select this component when designing PCI Express hot plug controllers requiring multi-channel support. The integrated thermal limiting and automatic retry features simplify protection circuit design. Verify that the 3.6 V maximum supply voltage aligns with the system power rails. Consider the TQFP-48 package constraints for board space and thermal dissipation requirements.
