FOR FAN MOTOR
SINGLE-PHASE FULL-WAVE
DRIVER
DESCRIPTION
The UTC F2970 is a single-phase full-wave bipolar driver
control IC with excellent efficiency for fan motor.
FEATURES
* 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=1connection,)
* 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
