MAX5960L Evaluation Kit/
Evaluation System
Evluate:/MAX5960L
General Description
Features
The MAX5960L evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount quad hot-plug controller
♦ Demonstrates PCI Express x16 Quad Hot-Plug
Design
®
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 demon-
strates the MAX5960L IC’s inrush current control, out-
put overcurrent/short-circuit protection, and input
undervoltage monitoring features.
♦ Independent Output Controls for Each Channel
12V and Up to 5.5A (Adjustable)
3.3V and Up to 3.3A (Adjustable)
3.3VAUX and Up to 0.550A
♦ Evaluates Hot-Plugging PCI Express x1, x4, x8,
or x16 Line Cards
♦ Demonstrates Input Inrush Current Control
♦ Demonstrates Output Overcurrent/Short-Circuit
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).
Protection
♦ Undervoltage Lockout Protection for 12V, 3.3V,
and 3.3V Auxiliary Supplies
♦ Configurable Power-On Reset (POR)
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.
♦ Independent On/Off Controls for Each Channel’s
12V/3.3V Main and 3.3V Aux Power
♦ Latched Output (MAX5960L) after Fault
Conditions; also Evaluates MAX5959A,
MAX5960A Autoretry
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
♦ Input/Output Interface Using MAX7313 I/O
®
Expanders (SMBus Interface) or Local Control
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.
♦ Can Be Controlled Locally Without Software
♦ Windows 98SE/2000/XP-Compatible Software
♦ Fully Assembled and Tested
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.
