Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.

*1: 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.
*2: When taking Hall bias from VCC, carry out bias to VCC with resistor R1 as shown in the figure. Linear drive is
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.
*3: When the Hall bias is taken from the HB pin, constant-voltage bias is made with about 1.5V. Therefore, the Hall
element can provide the output satisfactory in temperature characteristics.
*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.
In this case, insert the capacitor as shown in the figure.
