1 / 6 page UNISONIC TECHNOLOGIES CO., LTD F2867 Advance LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 6 Copyright © 2016 Unisonic Technologies Co., Ltd QW-R109-038.a VARIABLE SPEED SINGLE-PHASE FULL-WAVE PRE-DRIVER DESCRIPTION The UTC F2867 is a single-phase bipolar variable speed driving motor pre-driver that works with external PWM signal. A highly efficient, highly silent and low power consumption motor driver circuit can be achieved with a few external parts. This product is optimal for driving large scale fan motors requiring large air flow and large current such as servers and consumer appliances. FEATURES * Pre-driver for single-phase full-wave drive Low-saturation drive using external PMOS-NMOS enables high-efficiency low power-consumption drive. * External PWM input enabling variable speed control Separately-excited upper direct PWM (f=30kHz) control method enabling highly silent speed control. * Current limiting circuit incorporated Chopper type current limit at start. * Reactive current cut circuit incorporated Reactive current before phase change is cut to enable silent and low power-consumption drive. * Minimum speed setting pin Minimum speed can be set by set with external resistor. * Soft start setting pin * Lock protection and automatic reset functions incorporated * FG (rotation speed detection) output * Thermal shutdown circuit incorporated TSSOP-16 ORDERING INFORMATION Ordering Number Package Packing F2867G-P16-R TSSOP-16 Tape Reel |
