Ordering number : EN6215
LB1966M
Monolithic Digital IC
LB1966M
Fan Motor 2-Phase Half-Wave Driver
Features
• Dual power supply voltage design (5/12V) and wide voltage
handling range
• 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 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.
