Description
The MAX5960L evaluation kit (EV kit) is a fully assembled
and tested surface-mount quad hot-plug controller
printed-circuit board (PCB) with four PCI Express® hot-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 demonstrates
the MAX5960L IC's inrush current control, output
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 provided
to independently enable/disable each channels'
main (12V, 3.3V) and auxiliary supply (3.3V).
The MAX5960L EV kit can be reconfigured for evaluating
a x1, x4, or x8 PCI Express quad hot-plug design.
Alternatively, the EV kit can also be used to demonstrate
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
interface. Simple Windows® 98SE/2000/XP-compatible
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.
