Part Number: DAC81408EVM
Hi,
We would like to use the DAC81408 for developing the battery testing equipment and was using the EVM to do the verification.
However, we faced some short circuit issue. Just wondering if there is a power sequence between VDD and VCC? if so, what will be the required delay between these two nodes? Thank you.
Here is the test result table:

Result |
|
1st Trial |
VDD |
VCC |
VDD > 500mA, VCC > 100mA(CC mode) |
|
2nd Trial |
VDD |
VCC |
VDD > 500mA, VCC > 100mA(CC mode) |
|
3rd Trial |
VCC |
VDD |
VDD > 0mA, VCC = 2mA(CV mode) |
