MAX34460 Evaluation Kit Evaluates: MAX34460 General Description The MAX34460 evaluation kit (EV kit) provides the hardware and software graphical user interface (GUI) necessary to evaluate the MAX34460 PMBusK 12-channel voltage monitor and sequencer. The EV kit includes a MAX34460ETM+ installed, as well as four power supplies that can be sequenced, monitored, and margined by the IC.

MAX34460 Evaluation Kit Evaluates: MAX34460 The Connection menu item allows the user to connect to a desired device. Find Slave Addresses searches for all slave addresses connected to the I2C bus. To select a device, click Select Slave Address and all the slave addresses found are shown and are selectable. Slave addresses 18h and 34h are not selectable to prevent communicating with the alert response address and factory-programmed address.

MAX34460 Evaluation Kit Evaluates: MAX34460 Sequencing Graph Tab The Sequencing Graph tab sheet (Figure 2) displays the timing diagrams for all the channels. When the Power Up radio button is selected, the TON Delay (TON_DELAY 60h) and TON Max (TON_MAX_FAULT_LIMIT 62h) values are displayed on the graph. To change the TON Delay, click and drag the green vertical bar; to change TON Max, click and drag the red vertical bar.

MAX34460 Evaluation Kit Evaluates: MAX34460 Status Tab The Status tab sheet (Figure 5) displays all the faults, warnings, and device ID information. To read all the current output values, faults, and warnings, press the Read Status button or turn on Auto Polling. The fault and warning bits are read from STATUS_VOUT (7Ah), STATUS_MFR_SPECIFIC (80h) and STATUS_ TEMPERATURE (7Dh). The Polled values are read from READ_VOUT (8Bh) and READ_TEMPERATURE (8Dh).

MAX34460 Evaluation Kit Evaluates: MAX34460 Detailed Description of Hardware User-Supplied I2C Interface To communicate with the MAX34460 using a usersupplied I2C interface, first remove the J23 jumper to disconnect the USB I2C dongle. If the dongle is no longer desired, it can be separated from the EV kit by snapping the PCB at the scored line. Connect test points SDA, SCL, GND, and 5V to the off-board I2C interface. The I2C interface should operate at 3.3V.

MAX34460 Evaluation Kit Evaluates: MAX34460 Table 5. Troubleshooting SYMPTOM CHECK Are any of the LEDs illuminated? If yes, then the electronic fuse (U7) is in a fault state. Inspect for electrical shorts on the PCB and make sure that the PCB is not sitting on a conductive surface. If not, then exit the GUI and try running it again.
