Hot Swap Controllers datasheet and documents for MIC2341R-2YTQ
Hot Swap Controllers Overview
The MIC2341R-2YTQ is a dual-slot PCI Express hot-plug controller manufactured by Microchip Technology. It operates within a supply voltage range of up to 3.6 V and supports an operating temperature range from 0°C to 70°C. The device is housed in a TQFP-48 (7x7) surface-mount package. Key functional features include automatic retry capabilities, thermal limiting protection, and under-voltage lockout (UVLO). It is designed for safe insertion and removal of PCI Express cards in live systems.
Hot Swap Controllers Feature Summary
- Dual-slot architecture supporting simultaneous control for two PCI Express slots
- Integrated thermal limiting to prevent overheating during high-current events
- Automatic retry mechanism for robust connection management
- Under-voltage lockout ensures stable operation during power transitions
Hot Swap Controllers Applications
- PCI Express backplane systems requiring hot-swap capability
- Server and storage enclosure designs with dual-slot expansion
- Industrial equipment needing safe card insertion/removal
Hot Swap Controllers Procurement Notes
Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm pinout and feature set compatibility. Ensure the TQFP-48 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status as per the latest manufacturing notification. Check for any process change notifications that may affect long-term availability or material composition.
Hot Swap Controllers Selection Notes
Select this component when designing dual-slot PCI Express interfaces requiring integrated hot-plug management. The built-in thermal limiting and UVLO reduce external component count compared to discrete solutions. Verify that the 3.6 V maximum supply voltage aligns with your system's power rails. Consider the 0°C to 70°C operating range for environmental suitability.
Hot Swap Controllers Part Context
This part belongs to the MIC2341 family of hot-plug controllers. It is specifically engineered for PCI Express applications. The 'R' suffix typically indicates a specific tape-and-reel packaging variant. It serves as a specialized power management IC within the broader PMIC category.
