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-chan-

nel MOSFETs for the 12V and 3.3V outputs of each chan-

nel, 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

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 eval-

uation of the MAX5946L.

*EP = Exposed paddle.

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.
