TYPICAL APPLICATIONS
Designing with the TC648 involves the following:
(1) The temperature sensor network must be
configured to deliver 1.25V to 2.65V on VIN for 0%
to 100% of the temperature range to be regulated.
(2) The auto-shutdown temperature must be set with
a voltage divider on VAS (if used).
(3) The output drive transistor and base resistor must
be selected.
(4) If reset/shutdown capability is desired, the drive
requirements of the external signal or circuit must
be considered.
The TC642 demonstration and prototyping board
(TC642DEMO)
and the TC642
Evaluation
Kit
(TC642EV) provide working examples of TC648 cir-
cuits and prototyping aids. The TC642DEMO is a
printed circuit board optimized for small size and ease
of inclusion into system prototypes. The TC642EV is a
larger board intended for benchtop development and
analysis. At the very least, anyone contemplating a
design using the TC648 should consult the documen-
tation for both the TC642EV (DS21403) and
TC642DEMO (DS21401). Figure 5-1 shows the base
schematic for the TC642DEMO.
An Excel-based spreadsheet is also available for
designing the thermistor network for the TC64X fan
controllers. This file (TC64X Therm) is available for
