Device Overview

Summary

The MIC2341 is a dual-slot power controller supporting the power distribution requirements for Peripheral Component Interconnect Express (PCI Express®) Hot-Plug compliant systems. The MIC2341 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. These features provide comprehensive system protection and fault isolation.
