Preliminary

LINEAR INTEGRATED CIRCUIT

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.

SOP-18



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 t_R

* Kick-back absorption circuit are built in

* Current limiter function (The limiter value determined with R_f,

limit at I_O=480mA with R_L=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
