Fan Motor Driver
Single-Phase Full-Wave Driver
Overview
The LV8063TT is the driver IC with BTL linear output for single-phase fan motor, and that drives at high efficiency, low
power, and low noise by suppressing the reactive power.
The BTL output can be combined with the PWM control by an external signal, which is optimum for the note PC, the CPU
cooler, etc. that requires low power dissipation and low noise.
Functions
• Single-phase full-wave operating by BTL output (BTL amplifier gain : +43dB)
• Speed control available by PWM pin
• Hall bias output pin (VHB = 1.05V typ)
• Built-in Quick Start circuit
• FG(rotation signal) output pin (Open drain output)
• Built-in thermal-shutdown (TSD) circuit
• Built-in lock protection and automatic return circuit
