The MAX5946L evaluation kit (EV kit) is a fully assembled
and tested surface-mount, dual hot-plug controller circuit
board for two PCI Express® hot-plug slots. The circuit
uses a MAX5946L IC in a 36-pin thin QFN package. The
EV kit provides independent power control for the 12V,
3.3V, and 3.3V auxiliary outputs at two PCI Express-16
connectors. The EV kit demonstrates the MAX5946L IC's
inrush current control, output overcurrent/short-circuit
protection, and input undervoltage monitoring features.
The MAX5946L IC controls two separate external n-channel
MOSFETs for the 12V and 3.3V outputs of each channel,
respectively. Additionally, the MAX5946L has two
internal MOSFETs that control the 3.3V auxiliary outputs
of channels A and B. Switches on the EV kit are provided
to independently enable/disable each channels'
12V/3.3V and 3.3V auxiliary supply.
The MAX5946L EV kit can be reconfigured to evaluate an
x1, x4, or x8 PCI Express dual hot-plug design.
Alternatively, the EV kit can also be used to demonstrate
the MAX5946L hot-plug features without using the PCI
Express-16 connectors.
The EV kit includes a MAX7313 I/O expander that
enables communication through an SMBus™ interface
for the MAX5946L signals and some of the PCI Express
channel A and B signals. An SMBus interface board
(CMODUSB) can be used to enable PC communication
through the SMBus interface. Simple Windows®
98/2000/XP-compatible software is provided to access
the MAX7313 I/O expander registers at the bit level. The
MAX5946L EV kit can be used in local control without
any software.
Order the MAX5946LEVCMODU for a complete PC-based
evaluation of the MAX5946L. Order the
MAX5946LEVKIT if you already have a CMODUSB
SMBus interface board or do not require PC-based evaluation
of the MAX5946L.
* Some packages have variations, listed on the drawing. "PkgCode/Variation" tells which variation the product uses. Note that "+", "#", "-" in the part number suffix describes RoHS status. Package drawings may show a different suffix character.

Notes and Comments
Note: The MAX5946L EV kit software is provided with the
MAX5946LEVKIT. However, the CMODUSB interface board is
required to interface the EV kit to the computer when using the
software.
