TC647

TYPICAL APPLICATIONS
Designing with the TC647 involves the following:
(1) The temp 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 minimum fan speed (VMIN) must be set.
(3) The output drive transistor and associated circuitry
must be selected.
(4) The SENSE network, RSENSE and CSENSE, must
be designed for maximum efficiency while
delivering adequate signal amplitude.
(5) If shutdown capability is desired, the drive require-
ments 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 TC647 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 TC647 should consult the documen-
tation for both TC642EV and (DS21403) and
TC642DEMO (DS21401). Figure 5-1 shows the base
schematic for the TC642DEMO.
