3.4.4 Test Procedure with USB2ANY

For EVM operating with USB2ANY for Boost Mode or Battery Discharge Mode,

1. Set up the bench as shown in Figure 4-16.

2. Refer to the jumper setting described in Table 2-2.

JP1 needs to be set as all open.

JP2 needs to be set as all open.

JP3 needs to be default.

JP4 needs to be set as (1,2) closed for DA reference as current setting.

JP5 needs to be set as (1,2) closed for DA reference as voltage setting.

3. Set PS-High to 15 V and PS-Low to 3.6 V and turn on.

4. Set E-Load-High to CC mode 5 A and turn on.

5. Open USB2ANY explorer, click 'Select Interfaces' , choose the 'GPIO' and '12C'.

6. Open GPIO interface, set GPIO6 and GPIO7 to be output, 'GPIO6 =1' and 'GPIO7 = 0'.

7. Open I2C interface, write in proper codes to set the voltage reference setting Vset, Vset needs to be higher than battery voltage(3.6 V).

8. Write in proper codes to set the current reference setting Iset. The converter starts switching when the comp voltage reaches 0.65 V typically.

9. After the tests are done, the converter can be disabled by setting 'GPIO6 = 0'.

10. Turn off all the Power supplies and E-Loads.

For EVM operating with USB2ANY for Buck Mode or Battery Charge Mode,

1. Set up the bench as shown in Figure 4-16.

2. Refer to the jumper setting described in Table 2-2.

JP1 needs to be set as all open.

JP2 needs to be set as all open.

JP3 needs to be default.

JP4 needs to be set as (1,2) closed for DA reference as current setting.

JP5 needs to be set as (1,2) closed for DA reference as voltage setting.

3. Set PS-High to 15 V and PS-Low to 3.6 V and turn on.

4. Set E-Load-Low to CC mode 20 A and turn on.

5. Open USB2ANY explorer, Click 'Select Interfaces', then select 'GPIO' and 'I2C'.

6. Open GPIO interface, set GPIO6 and GPIO7 to be output, 'GPIO6 =1' and 'GPIO7 =1'.

7. Open I2C interface, write in proper codes to set the voltage reference setting Vset, Vset need to be higher than battery voltage(3.6 V).

8. Write in proper codes to set the current reference setting Iset. The converter starts switching when the comp voltage reaches 0.65 V typically.

9. After all the tests are done, the converter can be disabled by setting 'GPIO6 = 0'.

10. Turn off all the Power supplies and E-Loads.
