All test setups shown in the following figures assume the flat test cable with receptacle and test points is
attached to the connector J1 of the EVM.
2.2.1
Power UP Test
Test setup for power up test is shown in
Figure 4
. For these tests digital multi-metersfor DC voltage
measurements are set auto-range. MM1 is set for DC current measurements with expected range up to
500 mA. Here and in all test setups below, red arrows indicate positive terminals and black arrows indicate
return terminal.

WARNING
Before start testing make sure to follow all electrical safety and
ESD protection requirements implemented at your company!
1. Enable power supply PS1
2. Gradually increase the voltage at PS1 and monitor voltage using MM4 and current using MM1
3. Verify measured voltage and current in accordance to
Table 2
. If current or voltage is outside the
specified range, stop increasing the voltage at PS1 and return to initial stage
4. Gradually reduce the voltage at PS1 to 0 V and disable it
