LA6681MC

Ordering number : ENA2074 LA6681MC Monolithic Linear IC Single-phase Full-wave Fan Motor IC http://onsemi.com Overview 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. Functions Single-phase full-wave linear drive by BTL output. : Linear drive for further silence and the most suitable for fan motor for the notebook PC. 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) : High coil efficiency and small current drain. Small heat generation from IC itself FG output (Rotation detection output: Open collector output) High impedance of Hall input pin Heat protection circuit : The heat protection circuit suppresses the drive current to prevent burn or damage of IC when the large current flows due to output short-circuit and the IC chip temperature exceeds 180°C. Small package with high heat capacity Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage Output current Output withstand voltage FG output withstand voltage FG output current Allowable dissipation Symbol VCC max IOUT max VOUT max VFG max IFG max Pd max Conditions Mounted...
