THE TC64X/TC64XB FAN CONTROL EVALUATION BOARD
The TC64X/TC64XB Fan Control Evaluation Board (Figure 1-1) measures 4” x 6”. The
circuit board is populated with an 8-pin PDIP socket that can accommodate any of the
TC64X and TC64XB devices. While the evaluation kit is pre-configured for a 100 mA,
12V fan, it can be custom-configured for a user-specific combination of control and fan
requirements. A LED status indicator is also provided to give a visual indication of a fan
fault condition.
The TC64X/TC64XB Fan Control Evaluation Board is powered from an external power
supply (5V, 50 mA). The fan speed control signal can be provided by an external sensor,
an external voltage signal or the on-board potentiometer. Minimum speed setting and
auto-shutdown thresholds are conveniently set by a second potentiometer. Also included
are jumper-configurable options for setting the output stage configuration, the modulation
frequency and the input signal source. A SHDN/RESET switch is also available for
manually shutting down the fan or resetting the system.
