10.16 Temperature Sensing Capability
A temperature-sensitive voltage derived from the Band
Gap sensing on the die is buffered and available as an
analog input into the Analog Switch Cap Type A Block
ASA21. Temperature sensing allows protection of device
operating ranges for fail-safe applications. Temperature
sensing combined with a long sleep timer interval (to
allow the die to approximate ambient temperature) can
give an approximate ambient temperature for data acqui-
sition and battery charging applications. The user may
also calibrate the internal temperature rise based on a
known current consumption.
The temperature sensor input to the ASA21 block is
labeled VTemp, and its associated ground reference is
labeled TRefGND (see
FigureTitle
22,
