Overview

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

Functions

• Single-phase full-wave drive (16V to 1.2A output transistor incorporated)

• Variable speed function using thermistor input and external signal incorporated

→Enables silent and low-vibration variable speed control through direct PWM control with separately-excited upper

Tr

• 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
