LA6595DM

Overview

The LA6595T 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 detection 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 = 200mA)

• Built-in lock protection and automatic return circuits

• Built-in RD (Rotation Detection) output

• Thermal protection circuit

• Extra-small package (Micro8)
