General Description

The MAX5960L evaluation kit (EV kit) is a fully assem-

bled and tested surface-mount quad hot-plug controller

plug slots. The circuit uses a MAX5960L IC in an 80-pin

TQFP package. The EV kit provides independent power

control for the 12V, 3.3V, and 3.3V auxiliary outputs at

four PCI Express x16 connectors. The EV kit demon-

strates the MAX5960L IC’s inrush current control, out-

put overcurrent/short-circuit protection, and input

undervoltage monitoring features.

The MAX5960L IC controls two separate external

n-channel MOSFETs for the 12V and 3.3V outputs of

each channel, respectively. Additionally, the MAX5960L

has internal MOSFETs that control the 3.3V auxiliary

outputs of channels A, B, C, and D. Switches are pro-

vided to independently enable/disable each channels’

main (12V, 3.3V) and auxiliary supply (3.3V).

The MAX5960L EV kit can be reconfigured for evaluat-

ing a x1, x4, or x8 PCI Express quad hot-plug design.

Alternatively, the EV kit can also be used to demon-

strate the MAX5960L hot-plug features without using

the PCI Express x16 connectors.

The EV kit includes three MAX7313 I/O expanders that

enable communication through an SMBus™ interface for

the MAX5960L signals and some of the PCI Express

channel signals. A CMAXQUSB interface board can be

used to enable PC communication through the SMBus

software is provided to access each MAX7313 I/O

expander register at the bit level. The MAX5960L EV kit

can also be used in local control, without any software.

Order the MAX5960LEVCMAXQU for a complete PC-

based evaluation of the MAX5960L. Order the

MAX5960LEVKIT if you already have a CMAXQUSB

interface board or do not require PC-based evaluation

of the MAX5960L.
