General Description

The MIC2342 is a dual-slot power controller supporting the power distribution requirements for Peripheral Component Interconnect Express (PCI Express®) Hot-Plug compliant systems.

The MIC2342 provides complete power control support for two PCI Express slots, including the 3.3VAUX defined by the PCI Express standards.

Support for the 12V, 3.3V, and 3.3VAUX supplies includes programmable gate voltage slew-rate control, voltage supervision, programmable current limit, and circuit breaker functions.

Overview

MIC2342/2342R Dual-Slot PCI Express® Hot-Plug Controller General.

Key Features

provide comprehensive system protection and fault isolation. Additionally, in the event of an overcurrent fault on 3.3VAUX that “trips” the circuit breaker to cause the 3.3VAUX output to shut down, the MAIN outputs (3.3V and 12V) for the affected 3.3VAUX slot, A or B, will also be shut down. The MIC2341 controller provides truly independent output operation for MAIN and AUX. Data sheets and support documentation can be found on Micrel’s web site at: www. micrel. com. Features.
