MAX19000 Evaluation Kit

4_ _ _______________________________________________________________________________________

17) Start the MAX19000 EV kit software by opening

its icon in the Start_ |_ Programs menu. The EV

kit software main window appears, as shown in

Figure 1. The MAX19000 EV kit software places the

MAX19000 in drive mode.

18) Select the DCL/Channel_0 tab.

19) Set VCH to 6.2V by entering 6.2 into the VCH edit

box located inside the Voltage group box and press

the Enter key on the keyboard.

20) Set VCL to -2.2V by entering -2.2 into the VCL edit

box located inside the Voltage group box and press

the Enter key on the keyboard.

21) Set VDH to 1V by entering 1 into the VDH edit box

located inside the Voltage group box and press the

Enter key on the keyboard.

22) Set VDL to 0V by entering 0 into the VDL edit box

located inside the Voltage group box and press the

Enter key on the keyboard.

23) This places channel 0 into the drive-high mode.

24) Select the DCL/Channel_ 1 tab and repeat steps

19–22 to place the channel 1 into the drive-high

mode.

25) The TMPSNS test point monitors the MAX19000

junction temperature. Verify that the voltmeter does

not read higher than +4.2V (junction temperature

< +150NC).

26) Set the oscilloscope to 10MI high-impedance

mode.

27) Set the oscilloscope to trigger on the OUT0 chan-

nel, with the trigger level set to +0.5V. Set the time

base to 20ns per division. A 0 to +1V square wave

of 20MHz appears on the oscilloscope.
