LB1669, 1669M
2-Phase Unipolar Brushless Motor Driver
Overview
The LB1669, 1669M are 2-phase uniploar brushless motor
drivers. They make it possible to configure motor lock
protection and automatic recovery circuits with few extenal
components.

(4) Output protection function (C pin)
Capacitor pin used in forming an automatic recovery circuit. If rotation is stopped due to overload, the pin voltage level
increases and then forces the output to become inactive. In this case, after proper load adjustment, the output returns to the
‘drive’ mode from the ‘stop’ mode automatically. By changing the capacitor value, the lock detect time period can be set.
For 1 µF lock detection time about 2 seconds
lock protection time (output ON) about 1 second
(output OFF) about 6 seconds

Automatic Recovery Circuit C Pin Voltage
Rotation
1 When a fan is rotating, the capacitor is charged at 3 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 0.8 × VIN.
3 When the output is turned OFF, discharge occurs through the C at 0.44 µA (typ). If the lock is not released when the C
voltage drops to VTH2, the capacitor is charged to VTH1 again. (At this moment, the output is turned ON.)
These operations 2 and 3 are repeated at a cycle of approximately ton : toff = 1 : 6 to protect the 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 (pins B1 and B2)
These are the base pins for Darlington connected output transistors.
If radio noise is a problem, add a capacitor of 0.01 to 0.1µF or less.
(7) Thermal shutdown function
Shutdown the driver output in case of coil short-circuiting and abnormal IC heating.
