LB11660RV中文资料Half-pre Motor Driver, Single-Phase Full-Wave Drive, for Fan Motor数据手册ONSEMI规格书

描述 Description

The LB11660RV is a single-phase bipolar half pre-driver that can achieve high-efficient direct PWM drive with ease. It is ideal for driving small-sized cooling fans used in servers. The LB11660RV is provided with the RD (lock detection) output pin and the LB11660FV the FG (rotational speed detection) output pin, respectively.

特性 Features

• Single-phase full-wave drive (15V-1.5A output transistor built in) upper output Tr incorporated half pre-driver.
• Variable speed control by an external signal.
• Lowest speed setting possible.
• Current limiter circuit(the circuit actuated at IO = 1A when Rf = 0.5Ω, Rf determines the limiter value.)
• Kickback absorption circuit built in.
• Soft switching circuit achieves low power consumption, low loss, and low noise driving at a time of phase change.
• HB built in.
• Lock protection and automatic reset functions incorporated(including a circuit that changes the ON/OFF ratio according to the power supply voltage)
• RD (lock detection) output.
• Thermal protection circuit incorporated (design guaranteed).

应用 Application

• Fan Motor Drive
• Small-sized cooling fans used in servers
