TA8462F/FG
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8462F/FG
FAN MOTOR DRIVER IC
The TA8462F/FG is a 2 phase half−wave hall motor driver IC.
This IC is best suited for the fan motor driving.
The output current of this IC is 1.5 A (peak) and all functions
needed for fan motor driving have been incorporated into a 1 chip,
enabling it to largely reduce peripheral parts and a space, thus
realizing down−sizing.
Further, the TA8462F/FG is provided with the FG output pin
(outputs pulses proportional to the motor speed) and the RD
output pin (outputs the motor ON / OFF statues).
FEATURES
z Built−in Automatic Self Rotation Recovery Circuit After
Release of Motor Locking.
z Thermal Shutdown Circuit Incorporated.
z Operating Voltage: 4~15 V
z Recommended Operating Voltage: VCC = 5 V, 12 V
z No VCC−GND Reverse Connection Preventive Diode Required.
Weight : 0.09 g (Typ.)
The TA8462FG:
The TA8462FG is a Pb-free product.
The following conditions apply to solderability:
*Solderability

*solder bath temperature = 230°C
*dipping time = 5 seconds
*number of times = once
*use of R-type flux
2. Use of Sn-3.0Ag-0.5Cu solder bath
*solder bath temperature = 245°C
*dipping time = 5 seconds
*the number of times = once
*use of R-type flux
