LB11852FV
Overview
The LB11852FV is a single-phase bipolar driving motor pre-driver with a speed control function based on speed feedback.
With a small number of external parts, a highly efficient and very quiet variable-speed drive fan motor with low power
consumption and high rotational accuracy can be implemented. The LB11852FV, integrated in a miniature package, is best
suited for driving small fan motors requiring speed control.
Features
Single-phase full-wave driving pre-driver
With a PMOS-NMOS device used as the external power transistor, low saturation output and a single-phase
full-wave drive enable a high-efficiency drive with low power consumption.
Speed control circuit incorporated
Compared with open-loop control, a closed-loop control function that uses speed feedback to control the speed
makes it possible to improve the rotational speed accuracy and reduce the variations in the rotational speed caused
by fluctuations in the supply voltage or load. The separately excited upper direct PWM method is featured as the
variable speed system.
Variable speed control is possible with external PWM input or analog voltage input
The speed control input signal is compatible with PWM duty ratio and analog voltages.
Soft start circuit incorporated
Minimum speed setting pin
The minimum speed can be set using an external resistor.
Current limiting circuit incorporated
Chopper type current limit at startup or lock.
Reactive current cut circuit incorporated
Reactive current before phase changeover is cut, ensuring highly silent and low power-consumption drive.
Automatic resetting type constraint circuit incorporated
FG (rotational speed detection) output
Monolithic Digital IC
For Fan Motor
Single-phase Full-wave Pre-driver
