LA6581CL

Overview

Functions

The LA6581CL is single-phase bipolar fan motor is driven, through BTL output linear drive, at high efficiency, low power,

and low sound by suppressing the reactive power. Lock protection, rotary signal (FG, RD) circuits are incorporated, which

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 500-284k, 55dB) : Suitable for the equipment

• Low-voltage operation possible, with wide operable voltage range (3 to 16V)

• Low saturation output (Upper + lower saturation voltage : V O sat (total) = 0.3V typ, I O = 100mA) : High coil efficiency

• 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

• Ultraminiature package (ECSP2828-10 : 2.8×2.8×0.8mm

requiring silent operation, such as game equipment, CPU cooler, etc. because of its freedom from switching noise.

with low current drain. IC itself does not generate much heat.

above 180°C, the heat protection circuit suppresses the drive current, preventing IC burn and breakdown.
