Overview
Ordering number : ENN7192 Monolithic Digital IC 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.

5 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.
