general description the max5960l evaluation kit (ev kit) is a fully assem-bled 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-pintqfp 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? 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 interface. simple windows 98se/2000/xp-compatible software is provided to access each max7313 i/oexpander 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. pci express is a registered trademark of pci-sig corp. smbus is a trademark of intel corp. windows is a registered trademark of microsoft corp. features ? demonstrates pci express x16 quad hot-plug design ? 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 protection ? undervoltage lockout protection for 12v, 3.3v, and 3.3v auxiliary supplies ? configurable power-on reset (por) ? independent on/off controls for each channels 12v/3.3v main and 3.3v aux power ? latched output (max5960l) after fault conditions; also evaluates max5959a, max5960a autoretry ? input/output interface using max7313 i/o expanders (smbus interface) or local control ? can be controlled locally without software ? windows 98se/2000/xp-compatible software ? fully assembled and tested ordering information evaluate: max5959a/max5959l/max5960a/max5960l max5960l evaluation kit/ evaluation system ___________________________________________________ _____________ maxim integrated products 1 part type max5960levkit + ev kit MAX5960LEVCMAXQU + ev system 19-1009; rev 0; 10/07 for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com. note: the max5960l ev kit software can be downloaded from the maxim website at www.maxim-ic.com/evkitsoftware. however, the cmaxqusb interface board is required to inter- face the ev kit to a computer when using the software. + denotes lead-free and rohs-compliant. downloaded from: http:///

output power independently. external n-channel mosfets are used to control power to the 12v and 3.3v outputs of each channel. current-sensing resistors r32, r47, r34, and r48 are used for the 12v, and resistors r39, r53, r40, and r54 for the 3.3v outputs of the respective channel. internal mosfets on the max5960l control the 3.3v auxiliary outputs of each channel. if an overcurrent fault persists on either channel, the max5960l will shut down the respective channel. the fault is reported at the respective channels?open-drain power-good pin ( pwrgd_ ) and fault pin ( fault_ ). the max5960l power-on reset (por) is configured for160ms; however, the por can be reconfigured after installing resistor r18. slide switches are provided to enable/disable each channel? main output and auxiliary output indepen- dently when the smbus control is not used. jumpers ju1?u4 can be used to provide a presence-detect function for the respective channel if pci express cards are not used. momentary pushbutton switches sw1?w4 are provided to demonstrate the max5960l debounced logic gate outputs. the max5960l ev kit features green leds connected to each channel? 12v, 3.3v, and 3.3v auxiliary output that indicate if the respective output is currently pow- ered. red test points for the 12v and 3.3v outputs, vari- ous pci express signals, and other circuit signals such as the gate drive of each mosfet have been provided for probing on the ev kit board. all the ev kit? black test points are gnd points. the ev kit also features pcb pads for installing external resistors and capacitors near each mosfet gate termi- nal to increase the mosfet? gate-turn-on time. surface-mount 0805 case-size components can be installed at these locations. see figure 4 for each of the mosfet? gate r and c designators. the ev kit can be reconfigured for evaluating a x1, x4, or x8 pci express quad hot-plug design by replacing the appropriate current-sense resistor, r32, r34, r47, or r48. consult the appropriate pci express specification in the max5960l ic data sheet for selecting other designs. pcb pads are provided to demonstrate the max5960l hot-plug features without using the pci express x16 connectors. evaluate: max5959a/max5959l/max5960a/max5960l max5960l evaluation kit/ evaluation system ___________________________________________________ ____________________________________ 5 downloaded from: http:///
