LA6584
Overview
BTL Driver Single-Phase Full-Wave
Fan Motor Driver
The LA6584 is Single-phase bipolar fan motor is put into silent driving by means of BTL output linear drive, offering high
efficiency and power saving by suppressing the reactive current. Lock protection and rotation signal (FG, RD) circuits are
built in, ensuring optimum application to small fans for notebook PC, consumer equipment power supply, car audio system,
CPU cooler, etc. that require high reliability and low noise.

When Di to prevent breakdown in case of reverse connection is used, it is necessary to insert a capacitor Cr to
secure the regenerative current route. Similarly, Cr is necessary to enhance the reliability when there is no
capacitor near the fan power line.
To obtain Hall bias from VCC, carry out 1/2×VCC bias as shown in the figure. Linear driving is made through
voltage control of the coil by amplifying the Hall output. When the Hall element output is large, the startup
performance and efficiency are improved. Adjustment of the Hall element can reduce the noise further.
When the Hall bias is taken from the HB pin, constant-voltage bias is made with about 2.0V. Therefore, the Hall
element can provide the output satisfactory in temperature characteristics. Adjustment of the Hall output
amplitude is made with R1. (When VCC = 12V, the step *2 above proves advantageous for IC heat generation.)
Keep this open when not used.
When the wiring from the Hall output to IC Hall input is long, noise may be carried through the wiring.
In this case, insert the capacitor as shown in the figure.
