LB11967V-TLM-H

Привод двигателя, 1-фазный двигатель вентилятора, 6В до 16В питание, 16В/50мА/2 выхода, SSOP-20.

The LB11967V-TLM-H is a single phase full wave pre-driver for variable speed fan motor in 20 pin SSOP package. This monolithic digital single phase bipolar variable fan motor pre-driver works with an external PWM signal. A highly efficient, quiet and low power consumption motor driver circuit with a large variable speed can be implemented by adding a small number of external components. PNP-EMOS is used as an external power transistor, enabling high efficiency low consumption drive by means of low saturation output and single phase full drive. This device is optimal for driving large scale fan motors (with large air volume and large current) such as those used in servers and consumer products.
