Fan Motor Driver
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.
Micro8
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 : V sat (total) = 1.2V (typical), I = 200mA)
O
O
• Built-in lock protection and automatic return circuits
• Built-in RD (Rotation Detection) output
• Thermal protection circuit
• Extra-small package (Micro8)
