The LA6581CL is a low-saturation BTL output linear driving motor driver for single-phase bipolar fan motors. It features
quite, low power, high efficiency drive that suppresses reactive current. It is optimum for the notebook PC, consumer
equipment power supply, car audio system, CPU cooler, etc. that require high reliability and low noise.
• Single-phase full-wave linear drive with BTL output (gain resistance 500Ω to 284kΩ, 55dB) : Suitable for the equipment
requiring silent operation, such as game equipment, CPU cooler, etc. because of its freedom from switching noise.
• Low-voltage operation possible, with wide operable voltage range (3 to 16V)
• Low saturation output (Upper + lower saturation voltage : VOsat (total) = 0.3V typ, IO = 100mA) : High coil efficiency
with low current drain. IC itself does not generate much heat.
• High impedance of Hall input pin
• FG output (rotation speed detection output : open collector output)
• Heat protection circuit : When the large current flows because of output short-circuit, raising the IC chip temperature
°C, the heat protection circuit suppresses the drive current, preventing IC burn and breakdown.
• Ultraminiature package (ECSP2828-10 : 2.8mm×2.8mm×0.8mm typ) : Small substrate while allowing larger blades.
