LB11970FV中文资料Single-Phase Full-Wave Fan Motor Driver数据手册ONSEMI规格书

描述 Description

The LB11970FV is a single-phase full-wave driver for fan motor.

特性 Features

• Single-phase full-wave drive (16V to 1.2A output transistor incorporated)
• Variable speed function using thermistor input and external signal incorporated
• Current limiter circuit (limit at IO=480mA with RL=1Ω connection, the limiter value determined with Rf)
• Kick-back absorption circuit incorporated
• Low-consumption, low-loss, and low-noise drive enabled by the soft switching circuit during phase shift
• Regeneration Di incorporated with less external parts
• HB incorporated
• Lock protection and automatic reset functions incorporated
• FG (rotation detection) output
• Thermal shutdown circuit incorporated
