LB1966M
Fan Motor 2-Phase Half-Wave Driver
Package Dimensions
Features
unit: mm
• Dual power supply voltage design (5/12V) and wide voltage
handling range
3086A-MFP10S
• Built-in Hall amplifier with hysteresis (supports core
without commutating pole)
[LB1966M]
• 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 latch-type RD (restraint protection) output (Vosat =
0.2Vtyp at Io = 5 mA)

• Built-in output transistor with output withstand voltage
24Vmin/output current 500 mA (average), 1.2A (peak)
• 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.

Precautions
• Wiring layout for IN– and OUT1 must be designed to prevent interference. (If oscillation occurs for example when
output phase is switched, connect a capacitor with 0.1 µF or less between IN– and IN+ pins.)
• If CT pin is connected to GND, the lockup protection and restart functions are disabled.
• In a circuit configuration as shown above, a power supply/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.
