F2970
Overview
The UTC F2970 is a single-phase full-wave bipolar driver control IC with excellent efficiency for fan motor.
- Single-phase full-wave drive (16V to 1.2A transistors are built in) * Speed adjustment function by thermistor input and external signal incorporated →Enables silent and low-vibration variable speed control through direct PWM control with separately-excited upper tR * Kick-back absorption circuit are built in * Current limiter function (The limiter value determined with Rf, limit at IO=480mA with RL=1Ω connection,) * Low-consumption, low-loss, and low-noise drive enabled by the soft switching circuit during phase shift * HB incorporated * Lock protection and automatic reset functions incorporated * FG (rotation detection) output * Regeneration Di incorporated with less external parts * Thermal shutdown circuit incorporated
