The MIC2590B-2YTQ from Microchip Technology is a Dual-Slot PCI Hot Plug Controller that has been designed to support power distribution requirements for peripheral component interconnect (PCI) hot plug-compliant systems. It requires an input voltage of 0.8 - 2.1 V and an input current of up to 5 mA. This eFuse IC supports two independent PCI 2.2 slots and has an SMBus interface for slot power control and status. It supports +5 V, +3.3 V, +12 V, –12 V, +3.3 V AUX supplies as per PCI specification 2.2. This IC is designed with programmable inrush current-limiting and benefits from active current regulation that controls the inrush current. It is equipped with an electronic circuit breaker and has dual-level fault detection for quick fault response. This eFuse IC is available in a surface-mount package that measures 9 x 9 mm.
