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 the ...
