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.
F2867 Key Features
- Pre-driver for single-phase full-wave drive Low-saturation drive using external PMOS-NMOS enables high-efficiency low po

- 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-con
- 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 lockup detection) output (F2867-R)
