LA6581T
BTL Driver Single-Phase Full-Wave Fan Motor Driver
Overview
The LA6581T is a low-saturation BTL output linear
driving motor driver for single-phase bipolar fan motors. It
features quite, low power, high efficiency drive that
suppresses reactive current. It is optimal for use in
applications that require miniaturization and low noise,
such as CPU cooling fan motors and 5 to 12 V electronic
game products.
Functions and Features
• Single-phase full-wave linear drive with BTL output
(gain resistance 500-284k, 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 16 V)
• Low saturation output (Upper + lower saturation
voltage: VOsat(total) = 0.3 Vtyp, IO = 100 mA): High
coil efficiency with low current drain. IC itself does not
generate much heat.
• 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 above 180°C, the heat protection circuit
suppresses the drive current, preventing IC burn and
breakdown.
• Ultraminiature package (MSOP-8: 3.0 × 4.0 × 0.93 mm
typ): Small substrate while allowing larger blades.
