MAX8821 Evaluation Kit
Figure 2. Status: EV Kit Operational
20) Normal device operation is verified when EV Kit
Operational is displayed by the Status indicator as
shown in Figure 2. If the status indicator displays an
error, see the Troubleshooting section.
21) Select the LDO1 output voltage to be 3.2V.
22) Select the corresponding Enable box to enable
LDO1.
23) Verify the voltage read by DMM1 is 3.2V.
24) Select the corresponding Active Pull Down and
disable LDO1.
25) Verify the voltage read by DMM1 is 0V.
26) Select the LDO2 output voltage to be 3.3V.
27) Select the corresponding Enable box to enable LDO2.
28) Verify the voltage read by DMM2 is 3.3V.
29) Select the corresponding Active Pull Down and
disable LDO2.
30) Verify the voltage read by DMM2 is 0V.
31) Set LED1–LED6 to the 25.6mA setting.
32) Enable the ramp function for LED1–LED4 by select-
ing the corresponding Ramp boxes.
33) Select LED1 to a ramp-up and ramp-down time of
262ms.
