LB11850V
Monolithic Digital IC
For Fan Motor
Single-Phase Full-Wave Pre-Driver
with Speed Control Function
www.DataSheetO4Uv.ceomrview
The LB11850V is a single-phase bipolar fan motor driver with speed control function that works with a speed feedback
signal. A highly efficient, quiet and low power consumption motor driver circuit, with a high speed accuracy and large
variable speed can be implemented by adding a small number of external components.
This pre-driver is optimal for driving large scale fan motors (with large air volume and large current) such as those used
in servers and consumer products.
Functions and features
Pre-driver for single-phase full-wave drive
PMOS-NMOS is used as an external power TR, enabling high-efficiency and low-power-consumption drive by
means of the low-saturation output and single-phase full-wave drive.
On-chip speed control circuit
The speed control (closed loop control) using a speed feedback signal makes it possible to achieve higher speed
accuracy and lower speed fluctuations when supply voltage fluctuates or load fluctuates, compared with an open-
loop control system. Separately excited upper direct PWM control method is used as the variable-speed control
system.
External PWM input or analog voltage input enabling variable speed control
The speed control input signal is compatible with PWM duty ratio or analog voltages.
On-chip soft start circuit
Lowest speed setting pin
The lowest speed can be set with the external resistor.
Current limiter circuit incorporated
Chopper type current limit at start or lock.
Reactive current cut circuit incorporated
Reactive current before phase change is cut to enable silent and low-consumption drive.
Constraint protection and automatic reset functions incorporated
FG (speed detection), RD (lock detection) output
Constant-voltage output pin for hall bias
