TC64X/TC64XB Fan Control Evaluation Board User’s Guide
The output drive device can be either a SOT-23, TO-92 or a TO-220 transistor/
MOSFET, depending on the fan operating current and application. Resistor R 2 sets the
base drive current for this transistor. The configuration, as shipped from the factory,
consists of a 2N2222A transistor and a 1.1 k ? base resistor, which will drive a BDC fan
with an operating current of 100 mA or less. Larger fans can be driven with a different
combination of base resistor and output transistor. Fan commutation pulses are sensed
by pin 5 of the TC64X and TC64XB devices through R 3 and C 5 . Table 2-2 shows
suggested values for R 3 for various fan current ratings. The TC64X/TC64XB
Evaluation Kit is shipped from the factory with a 4.7 ? resistor installed for R 3 and a
0.1 μF capacitor installed for C 5 .
A fault visual indicator is also provided to facilitate experimentation. The FAULT LED is
driven active by Q 4 whenever the FAULT output of the TC64X/TC64XB device goes
