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)
• Built-in FG output (Vosat = 0.2Vtyp at I_O = 5 mA)
• Built-in output transistor with output withstand voltage

• Built-in thermal protection circuit
• 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.
