Product Description
The LA6581T is a low saturation, full wave, BTL output motor driver for single phase bipolar fan motors. It features low power and high efficiency drive that suppresses reactive current. It is optimal for use in applications that require miniturization and low noise such as CPU cooling fan motors and 5 to 12V electronic game products.

Features |
| |
|
-
Single phase, full wave linear drive with BTL output (gain resistance 500 Ωto 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
|
-
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.
|
-
Ultraminiature package (MSOP8: 3.0mm4.9mm0.93mm typ) : Small substrate while allowing larger blades.
|
-
FG output (rotation speed detection output : open collector output)
