MIC2590B Datasheet Dual-slot Pci Hot Plug Controller

Manufacturer: Micrel Semiconductor (now Microchip Technology)

Overview: MIC2590B Micrel MIC2590B Dual-Slot PCI Hot Plug Controller Final Information.

General Description

The MIC2590B is a power controller supporting power distribution requirements for Peripheral ponent Interconnect (PCI) hot plug pliant systems incorporating the Intelligent Platform Management Interface (IPMI).

The MIC2590B provides plete power control support for two PCI slots including the 3.3VAUX defined by the PCI 2.2 specification.

Support for +5V, +3.3V, +12V and –12V supplies is provided including programmable constant-current inrush limiting, voltage supervision, programmable current limit, fault reporting and circuit breaker functions which provide fault isolation.

Key Features

  • Supports two independent PCI 2.2 slots.
  • SMBus interface for slot power control and status.
  • +5V, +3.3V, +12V,.
  • 12V, +3.3VAUX supplies supported per PCI specification 2.2.
  • Programmable inrush current-limiting.
  • Active current regulation controls inrush current.
  • Electronic circuit breaker.
  • Dual level fault detection for quick fault response without nuisance tripping.
  • Thermal isolation between circuitry for slot A and sl.
