Hi,
I am using ADM1166 for monitoring & sequencing the supplies in my board.
All the charge pump output of the ADm1166 i.e. PDO1 to PDO6 should give a output voltage of 12V.
PDO1 to PDO5 is giving a output voltage of 12V.
But PDO6 is not giving 12V instead it is giving a less voltage between 0.075 to 0.15V.
The PDO6 pin & ground impedance is 442ohm & the impedance of other outputs i.e. PDO1 to PDO5 to ground is 1.5Mohm.
I am suspecting the ADM1166 sequencer CONFIGURABLE OUTPUT DRIVER (HV) for the particular channel gone bad.
Can you suggest how the output driver would have failed.
Regards,
Soumya S
