: High coil efficiency with low current drain. Additionally, IC itself generates only small heat.
•
Built-in lock protection and automatic reset circuits
•
Built-in FG & 1/2FG outputs
•
Built-in Hall bias (VHB = 1.5V)
•
Thermal protection circuit
: When the large current flows due to output short-circuit and the IC chip temperature exceeds 180°C, this protective
circuit suppresses the drive current to prevent burn and damage to IC.

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.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

*1 : When the breakdown protective DI at reverse connection is to be used, it is necessary to insert the capacitor Cr to
secure the regenerative current route. Similarly, Cr must be provided to enhance the reliability when there is no
capacitor near the fan power line.
*2 : To obtain Hall bias from VCC, carry out 1VCC 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.
*3 : To obtain Hall bias from the HB pin, carry out constant-voltage bias at about 1.5V, which enables the Hall
element to generate the stable Hall 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.
