2 / 8 page SP2526EB/02 SP2526 Evaluation Board Manual © Copyright 2000 Sipex Corporation 2 SP2526 EVALUATION BOARD The next two sections describe the SP2526 Board Layout and Using the SP2526 Evaluation Boards. A table of SP2526 Pin Assignments is also included with details on Input/Output pin function. A SP2526 Evaluation Board List of Materials table is provided with some manufacturers part numbers to use as a reference. Finally, a schematic and drawings of the PC Board Layout are included of the SP2526 Evaluation Board. BOARD LAYOUT The SP2526 Evaluation Board has been designed to easily and conveniently provide access to all Inputs and Outputs of the SP2526 device under test. Position the board with the silkscreen lettering upright (see Figure 1 Component Layout) and you will see the SP2526 SOIC labeled U1 in the center right of the board, and around it the Capacitors C1,2,3 and Ferrite Beads F1-4 forming the Dual USB Supervisory Switch. The SP2526 Evaluation Board provides solder pads to connect wires to an external power supply and load, as well as Test Point Posts to monitor the Input and Output Voltages at these connections to the SP2526. The SP2526 PC Board Layout has been designed with low resistance input and output connections of 2m Ω each to provide the lowest On-Resistance for utilizing the USB Switch. The PC Layout is given in Figures 1-3 for the user as an aid in designing a low resistance USB switch on a PC board. The PC board used has 1oz Copper with V IN, Ground, VOUT traces of at least 0.1inch width for 5m Ω/inch or looked at another way as 0.5m Ω/square. This means to maintain a trace resistance of only 2m Ω, you need to have only 4 squares of trace from one end to another. Resistance is further reduced by some additional wide V IN, Ground and VOUT connections on the bottom side of the PC board which are connected to the top side with large through-hole connections. For best results with on-resistance in the ferrites used for EMI suppression in the Output and Ground connections, through-hole ferrite beads were used for F1-4, yielding 2m Ω per input or output connection versus using surface-mount size 0805 ferrite beads which yielded 5m Ω per input or output connection. USING THE EVALUATION BOARD The SP2526 Evaluation Board can be connected to a power supply using a pair of wires soldered to the solder pads marked provided “VIN” and “GND”. It is good practice to not switch power on until power connections are made to the evaluation board. Powering Up & Using the SP2526 Circuit V IN — U1-7 — Solder wire to VIN solder pad on component side of board and connect to external Power Supply positive. V IN = +3.0V to +5.5V. Connect Voltmeter positive or Oscilloscope probe to V IN test point post to monitor actual voltage input to PC board. GND — U1-6 — Solder wire to GND solder pad on component side of board and connect to external Power Supply negative. Connect Voltmeter negative or Oscilloscope probe ground to GND test point post to monitor actual voltage input to PC board. OUTA — U1-8 — Solder wire to OUTA solder pad on component side of board and connect to external load. Connect Voltmeter positive or Oscilloscope probe to OUTA test point post to monitor actual voltage output at the PC board. GNDA — Solder wire to GNDA solder pad on component side of board and connect to external LoadA return. Connect Voltmeter negative or Oscilloscope probe ground to GND test point post to monitor actual voltage input to PC board. OUTB — U1-5 — Solder wire to OUTB solder pad on component side of board and connect to external load. Connect Voltmeter positive or Oscilloscope probe to OUTB test point post to monitor actual voltage output at the PC board. GNDB — Solder wire to GNDB solder pad on component side of board and connect to external LoadB return. Connect Voltmeter negative or Oscilloscope probe ground to GND test point post to monitor actual voltage input to PC board. |
