• Dual power supply voltage design (5/12V) and wide voltage
handling range
• Built-in Hall amplifier with hysteresis (supports core
without auxiliary electrode)
• Built-in lockup protection and automatic recovery circuits
(External capacitor for rotation detection need only be 0.1
µF, allowing compact, cost-saving design)

SANYO : MFP10S
• Compact, high-temperature resistant MFP-10 package
reduces external parts count and mounting space, therefore
making this IC support the motors with a wide range of
sizes and speeds.

Precautions
–
• Wiring layout for IN and OUT1 must be designed to prevent interference.
• If the wiring between the Hall element and the IC input is long, noise interference may lead to chattering in the FG
+
–
output waveform. In this case, insert a capacitor with 0.01 to 0.001 µF between IN and IN .
• If CT pin is connected to GND, the lockup protection and restart functions are disabled.
• In a circuit configuration as shown above, a current-GND reverse connection will cause a current to flow as follows:
GND -> OUT -> coil -> power supply. The magnitude of this current is limited by the coil resistance. If it is less
than 500 mA, the IC will not be destroyed. If required, insert a diode between V and the coil.
