LA6581MC
Monolithic Linear IC
Fan Motor Driver
BTL Driver Single-Phase
Full-Wave
http://onsemi.com
Overview
The LA6581MC 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 optimal for use in applications
that require miniaturization and low noise, such as CPU cooling fan motors and 5 to 12V electronic game products.
Functions
• 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 above 180°C, the heat protection circuit suppresses the drive current, preventing IC burn and
breakdown.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high
current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
