Manufacturer: Microchip Technology

Categories: Hot Swap Controllers

Quality Control: Learn More

Microchip Technology's MIC2591B-2BTQ is a 6-channel Hot Plug Controller designed for advanced power management applications. This device facilitates safe insertion and removal of PCI Express® compliant boards from live backplanes. It features configurable current limiting, fault timeout, and slew rate control, offering robust protection against overcurrent conditions. Integrated safety mechanisms include latched fault reporting, SMBus communication for system monitoring, thermal limit protection, and undervoltage lockout (UVLO). The MIC2591B-2BTQ incorporates internal switches for flexible power routing. Supplied in a 48-TQFP (7x7) package, it is suitable for surface mount applications operating within a temperature range of 0°C to 70°C. This component is frequently utilized in high-availability server systems, telecommunications infrastructure, and other demanding computing environments requiring reliable hot-swapping capabilities.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
