LA6586T Datasheet, PDF (1/8 Pages) Sanyo Semicon Device – BTL Driver Single-Phase Full-Wave Fan Motor Driver

Ordering number : ENN8348B
LA6586T
Monolithic Linear IC
BTL Driver Single-Phase Full-Wave
Fan Motor Driver
Overview
The LA6586T 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 (MSOP10)
