F2867
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. 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=30k Hz) 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...
