Overview
The LA6586FA is Single-phase bipolar fan motor is put into silent driving by means of BTL output linear drive,
offering high efficiency and power saving by suppressing the reactive current. Lock protection and rotation signal
(FG, RD) circuits are built in, ensuring optimum application to small fans for notebook PC, consumer equipment
power supply, car audio system, CPU cooler, etc. that require high reliability and low noise.
Functions
• Single-phase full-wave linear drive by BTL output (gain resistance 1kΩ-360kΩ, 51dB)
• Low-voltage operation possible, with wide operating voltage range (2.2 to 14.0V)
• Low saturation output (Upper + lower saturation voltage : Vosat (total)=1.2Vtyp, IO=200mA)
• Built-in lock protection and automatic reset circuits
• Built-in FG&RD outputs
• Built-in Hall bias (VHB=1.3V)
• Thermal protection circuit
• Extra-small package (Micro10)

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.
