Quick Start
Required Equipment
Before beginning, the following equipment is needed:
? MAX16050 EV kit
supply to the U1_VCC and U2_VCC test points.
Connect the ground terminal of this power supply to
the respective GND test points.
4) Connect the positive terminal of a 5V power supply
to the VPULLUP test point. Connect the ground ter-
?
?
DC power supplies: 3.5V/100mA, 5V/50mA
2-channel oscilloscope
minal of this power supply to the GND test point.
5) Connect oscilloscope channels 1 and 2 to the
U1_ RESET and U2_ RESET test points, respectively.
Procedure
The MAX16050 EV kit is a fully assembled and tested
surface-mount board. Follow the steps below to verify
board operation. Caution: Do not turn on the power
supplies until all connections are completed.
1) Verify that headers J1 and J2 and jumpers
JU1–JU14 are configured for demo mode configu-
ration (see Table 1).
2) Verify that switches SW1 and SW2 are set to the off
position.
Connect the ground leads to the nearby black GND
test points.
6) Turn on the VCC power supply and adjust the volt-
age to 3.5V.
7) Turn on the VPULLUP power supply and adjust the
voltage to 5V.
8) Verify that both U1_ RESET and U2_ RESET signals
are high.
9) The EV kit is ready for further testing.
