DC Fan Motor Drivers
Overview
The LB1662D, 1662M are 2-phase brushless motor drivers
operated from 5 V power supply. Motor Lock protection and
automatic return can be provided with a minimum number of
external parts.

LB1662D, 1662M
1 When a fan is rotating, the capacitor is charge at 2.8 µA (typ) and discharged through the C with pulses according to the
rotational speed.
2 When a fan is locked, no discharge occurs through the C and the C voltage rises, turning OFF the output at VTH1 (0.7 ×
VIN).
3 When the output is turned OFF, discharge occurs through the C at 0.38 µA (typ). If the lock is not released when the C
voltage drops to VTH2 (0.38 × VIN), the capacitor is charged to VTH1 again. (At this moment, the output is turned ON.)
These operations 2 and 3 repeated at a cycle of approximately tON : tOFF = 1 : 7 protect a motor.
4 If the lock is released when the C voltage drops to VTH2, the output is turned ON, starting rotation.
(5) Rotation detect signal (RD pin)
Open collector output (Drive mode: ‘‘L’’, Stop mode: ‘‘H’’)
(6) Radio noise reducing (B1 and B2 pins)
These are the base pins for Darlington connected output transistors. If radio noise is a problem, add a capacitor of
approximately 0.01 to 0.1 µF between B1 and B2, or 0.001 µF to 0.01 µF between OUT and B.
