Preliminary
LINEAR INTEGRATED CIRCUIT
FOR VARIABLE SPEED FAN
MOTOR SINGLE-PHASE
FULL-WAVE PRE-DRIVER
DESCRIPTION
The UTC F2967 is a single-phase fan motor pre-driver IC.
This IC has variable speed function that works with an external
Pulse-Width Modulation signal. A quiet and low power
consumption motor driver circuit can be implemented by adding a
small number of external components.
This IC is optimal for driving large scale fan motors (with large
air volume and large current) such as those used in servers and
consumer products.
FEATURES
* Single-phase full-wave drive
* Variable speed control with External PWM input
* Current limiter circuit
* Reactive current cut circuit
* Compatible with 12V, 24V, and 48V power supplies
* Minimum speed setting pin
* Reference voltage output pin for Hall bias
* automatic reset and Lock protection functions incorporated
* (Rotation speed detection), RD (Lock detection) output
