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
