Microchip Technology MIC2590B-2YTQ

The MIC2590B-2YTQ is a robust, high-performance dual-slot PCI bus hot swap controller designed by Microchip Technology to provide safe insertion and removal of cards into live backplanes. It is an ideal solution for managing hot-swap operations in systems that require high reliability and precision, such as servers, RAID systems, and telecommunications equipment.

This controller is specifically engineered to handle the electrical transients and power demands associated with hot swapping PCI cards. It ensures that the system remains stable and operational during card insertion and removal, preventing glitches and faults that could otherwise disrupt the bus or damage sensitive components.

Key Features:

• Integrated Power Control: The MIC2590B-2YTQ features built-in power control circuitry that manages the inrush current during card insertion, thereby protecting the backplane's power supply and distribution network.
• Dual-Slot Support: It is capable of controlling two independent slots, making it an efficient choice for systems with multiple expansion cards.
• Programmable Current Limit: Designers can set the current limit to match the requirements of their specific application, ensuring optimal performance and protection.
• Fault Management: The controller provides comprehensive fault management capabilities, including overcurrent protection and thermal shutdown, to safeguard against potential damage from abnormal operating conditions.
• LED Indicators: Onboard LED drivers indicate the status of each slot, providing visual feedback on the operation and any fault conditions.
• Glitch Filtering: The device includes glitch filtering on the PCI stop and reset signals to ensure stable communications on the bus during hot swap events.

The MIC2590B-2YTQ is offered in a 48-lead thin quad flat pack (TQFP) package, which is suitable for space-constrained applications. Its robust design and comprehensive feature set make it a reliable choice for system designers looking to implement hot swap functionality with minimal disruption to the host system. With Microchip's commitment to quality and support, the MIC2590B-2YTQ stands out as a superior choice for managing hot-swap operations in critical systems.
