More dodgy components, this time from our friends at Maxim (c/o Motorola)

The DS2502 datasheet is HERE

UPDATE:
Maxim have admitted the problem and have fixed everything without fuss.

It turns out the firmware is intended for Motorola phone batteries:

The Clock Drift PCBs

Real data collected with the sine fit envelope.
And results showing the same characteristic result over a slow temperature ramp.
