Hello.I have a question. please tell me.
The designed board is equipped with an LTC2974.
I will write to the LTC2974 via DC1613A.
Also, 5V is applied to Vpwr, and VDD33=3.3V and VDD25=2.5V can be confirmed.
However, when I connect the DC1613A to the board with power on and start "LTpower Play", the LTC2974 is not detected.
This will not occur if "MFR_SPECIAL_ID" is 0x0215.
It seems to occur only when "MFR_SPECIAL_ID" is 0x210.
When I run a product with MFR_SPECIAL_ID of 0x210 with the latest LTpowerplay Is it compatible?
(Looking at the LTC2974 datasheet, the "MFR_SPECIAL_ID" can be 0x0212, 0x0213, etc., depending on the revision.)
If possible, what is the cause and how can it be remedied?
