Fan Motor 2-Phase Half-Wave Driver
Features
Package Dimensions
• Dual power supply voltage design (5/12V) and wide voltage unit: mm
handling range
3032B-MFP8
(3V also supported for rotation functions only)
[LB1960M]
• Constant-voltage Hall bias power supply (1.3V across HB-
GND) assures stable Hall output over entire temperature and
power supply voltage range. External limiting resistor not

required.
• Built-in Hall amplifier with hysteresis (supports core
without commutating pole)
• 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 thermal protection circuit
• Compact MFP-8 package. Low external parts count, easy
wiring, and small PCB area allow use also with miniature
fan motors.
