Unisonic Technologies F2867
F2867 is a single-phase bipolar variable speed driving motor pre-driver that works with external PWM signal. This product is optimal for driving large scale fan motors requiring large air flow and large current such as servers and consumer appliances.DESCRIPTION
The UTC A highly efficient, highly silent and low power consumption motor driver circuit can be achieved with a few external parts. UTC F2867-R is with RD option and UTC F2867-F with FG.●
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 * Thermal shutdown circuit incorporated * FG (rotation speed detection) output (F2867-F) * RD(latch-type loc...
