When I used 12V for ADM1278 and without EN pin. But I can read ADM1278 register information via I2C bus.
Is it normal operation behavior for ADM1278?
I don’t want to get any I2C ack from ADM1278 if I disable it.
Would you kindly help to comment…
Dear ADI Expert,
Is ADM1278-1AACPZ-RL still active? why it didn't show in ADM1278's datasheet?
And why it didn't show ADM1278-1AACPZ-RL
Packing Qty in webpage? Is possible to revise this in datasheet?
The ADM1278 start-up ramp rate is determined by the capacitance at the GATE pin of the IC. This is a combination of the FET gate and an additional capacitor that you add. You can refer to the ADM1278 datasheet, page 26, in the section called…
Ren . THANKS YOU SO MUCH.
I have another question with you, If OCP trigger and into latch mode.
May I use enable pin for wake up ADM1278 lives ? or the only way is remove VCC and charge 12V again?
Our customer request the OCP fault event need keep…
Thanks for your reply, due to customer will use ADM1278-2A for 2nd source.
Can I connect ADM1278-1A's pin9 , pin10 which are NIC (not internal connect) to Vcap?
Or if I use ADM1278-1A, I can't connect any pin to NC pin?
We are confronted with ADM1278
We test ADM1278 on the PCB, and reach the PWGIN pin enable condition as below
But PWGIN pin always still stay disable status
If there is any another condition will cause ADM1278 PWRGD pin disable
ADM1278 alert setting
After we set ADM1278 alert threshold values, will ADM1278 reset alert signal by itself (like initialization)?
-- We set OC alert, UV alert values, set PMON_CONFIG (0xD4), ALERT1_CONFIG (0xD5) and we can observe a GPIO 1 alert#…
About ADM1278 for HSC application placement.
Since our board size is small,so Rshunt and MOS are place far away from controller.
It is ok for ADM1278 HSC?
Hello ADI expert,
As title, Customer is using ADM1278 for server application and they wondering to know whether ADM1278 can support Intel Node Manager 4.0?
