The LA6681MC drives the single-phase bipolar fan motor, through low-saturation BTL output linear drive, silently and at high efficiency with suppressed reactive power while saving power. This product is the most suitable for the CPU cooler fan motor operating on 5V power for notebook PC, which is required to be compactness and low noise.

• Single-phase full-wave linear drive by BTL output.
• Operable at low voltage and over a wide operation voltage range (2.0 to 7.0V)
• Low saturation output (Upper + lower saturation voltages: VOsat (total) = 0.32V typ, IO = 400mA)
• FG output (Rotation detection output: Open collector output)
• High impedance of Hall input pin
• Heat protection circuit
• Small package with high heat capacity
