1 / 9 page UNISONIC TECHNOLOGIES CO., LTD F2967 Preliminary LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 9 Copyright © 2013 Unisonic Technologies Co., Ltd QW-R109-036.a 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 TSSOP-20 ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free F2967L-P20-T F2967G-P20-T TSSOP-20 Tube F2967L-P20-R F2967G-P20-R TSSOP-20 Tape Reel |
