Description
The UTC F2970 is a single-phase full-wave bipolar driver control IC with excellent efficiency for fan motor.
Features
- S.
- 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 b.
