General Description
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.
Data sheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
