MIC2591B-2BTQ-TR

Hot Swap Controllers Overview

The MIC2591B-2BTQ-TR is a dual-slot PCI Express hot-plug controller manufactured by Microchip Technology. It supports two independent PCI Express slots and features an SMBus interface for slot power control and status ADC. The device includes two general-purpose input pins suitable for application interfaces and complies with PCI Express v1.0a hot-plug power control standards. Key electrical specifications include 12V and 3V fast-trip thresholds, a 100mV threshold setting, and a 3.3VAUX current limit of 0.375A. It is housed in a 48-pin TQFP package.

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing from distributors, as standard ordering information lists '2BTQ' without the reel designation. Confirm RoHS compliance status directly with the manufacturer or authorized suppliers, as historical data may vary. Ensure the supply chain source provides official Microchip documentation to validate the part number authenticity and revision level before procurement.

Hot Swap Controllers Selection Notes

Select this component for designs requiring dedicated hardware management of two PCI Express slots via SMBus. The 100mV threshold option distinguishes it from the 150mV variant. Consider the 48-pin TQFP footprint for PCB layout constraints. Verify that the system architecture utilizes SMBus for power sequencing and that the 0.375A auxiliary current limit meets the target card requirements.

Hot Swap Controllers Part Context

The MIC2591B series serves as a specialized controller for managing power delivery and status monitoring in multi-slot PCI Express environments. It integrates protection mechanisms and communication interfaces to facilitate safe insertion and removal of expansion cards. This specific model represents a variant within the broader family designed for high-reliability computing applications.
