Overview
The LV8068V is single-phase bipolar fan motor is driven, through BTL output linear driver, at high efficiency, low
power, and low noise by suppressing the reactive power. The BTL output can put PWM control by an outside signal
together, which is optimum for the CPU cooler, etc.
Functions
• Single-phase full-wave operating by BTL output (BTL amplifier gain : +49dB)
• Speed control available by PWM input
• The characteristic of the motor rotational speed adjust by “VCONT” voltage
• The characteristic of the motor rotational minimum speed adjust by “RMI” voltage
• Hall bias output terminal (VHB = 1.32V (typ))
• Built-in Quick Start circuit
• Startup support function (50% Duty Start)
• FG (rotate detection) output terminal (Open drain output)
• RD (Lock detection) output terminal (Open drain output)
• Built-in Current Limiter circuit (limit at IO = 250mA with Rf = 1 connection, the limiter value determined with Rf.)
• Built-in lock protection and automatic return circuit
• Built-in thermal shut-down (TSD) circuit
