• Manufacturer Part Number: la6588m
• Description: 24v Power Supply, Btl Output Linear Drive Single-phase Fan Motor Ic
• Manufacturer: Sanyo Semiconductor Corporation

*1: When Di to prevent breakdown in case of reverse connection is used, it is necessary to insert a capacitor Cr to secure
*2: When taking Hall bias from V CC , carry out bias to V CC with resistor R1 as shown in the figure. Linear drive is
*3: When the Hall bias is taken from the HB pin, constant-voltage bias is made with about 1.5V. Therefore, the Hall
*4: Keep this open when not using.
*5: When the wiring from the Hall output to IC Hall input is long, noise may be carried through the wiring.
the regenerative current route. Similarly, Cr is necessary to enhance the reliability when there is no capacitor near the
fan power line.
achieved through voltage control of the coil by amplifying the Hall output. With large Hall element output, the start
performance and efficiency are improved. Noise can be reduced further by adjusting the Hall element.
element can provide the output satisfactory in temperature characteristics.
In this case, insert the capacitor as shown in the figure.
