LB11970FV Datasheet | SANYO

Ordering number : ENA0707 .. Monolithic Digital IC For Fan Motor Single-phase Full-wave Driver 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...
