FAN MOTOR DRIVER IC
The TA8473F/FG and TA8473FN/FNG are fan motor driver ICs.
The output current is 0.4 A (AVE.) and all functions needed for
fan motor driving have been incorporated into 1 chip.
These are provided with the function to automatically change the
motor speed by detecting ambient temperature through the
externally mounted thermistor.
Furthermore, the TA8473F/FG and TA8473FN/FNG are provided
with the noise reduction terminal, the FG terminal to output
pulses proportional to the motor speed and the RD terminal to
detect the motor status.
FEATURES
z Built−in automatic self rotation recovery circuit after release
of motor locking.
z Thermal shutdown circuit incorporated.
z Operating voltage : 6~13.8 V
z 2 kind of speed of full−speed and half−speed are variable
according to ambient temperature.
z Speed change point temperature is externally settable.
