Monolithic Linear IC
BTL Drive Single-Phase Full-Wave
Fan Motor Driver
Overview
The LA6585T is a single-phase bipolar fan motor driver that achieves quite operation, power savings, silent operation and
high efficiency that suppresses reactive current through BTL output linear drive. It provides lock protection and rotation
signal circuits on chip, and is optimal for applications that require high reliability and low noise, such as notebook personal
computers, power supplies in consumer electronic equipment, car audio, and CPU cooling systems.
Features
• BTL output single-phase full-wave linear drive (gain resistor : 1 to 360kΩ, 51dB)
• Supports low-voltage drive and features a wide usable voltage range (2.2 to 14.0V)
• Low saturation output (high side + low side saturation voltage : Vosat (total) = 1.2V (typical), IO = 250mA)
• Built-in lock protection and automatic return circuits
• Built-in FG output
• Built-in Hall sensor bias (VHB = 1.5V)
• Thermal protection circuit
• Small-sized, high thermal capacity package
