PRELIMINARY  
Brushless DC Motor Controller  
FEATURES  
DESCRIPTION  
• Two Quadrant and Four Quadrant  
The UCC3626 motor controller IC combines many of the functions re-  
quired to design a high performance, two or four quadrant, 3-phase,  
brushless DC motor controller into one package. Rotor position inputs  
are decoded to provide six outputs that control an external power stage.  
A precision triangle oscillator and latched comparator provide PWM mo-  
tor control in either voltage or current mode configurations. The oscilla-  
tor is easily synchronized to an external master clock source via the  
SYNCH input. Additionally, a QUAD select input configures the chip to  
modulate either the low side switches only, or both upper and lower  
switches, allowing the user to minimize switching losses in less de-  
manding two quadrant applications.  
Operation  
• Integrated Absolute Value Current  
Amplifier  
• Pulse-by-Pulse and Average Current  
Sensing  
• Accurate, Variable Duty Cycle  
Tachometer Output  
• Trimmed Precision Reference  
• Precision Oscillator  
The chip includes a differential current sense amplifier and absolute  
value circuit which provide an accurate reconstruction of motor current,  
useful for pulse by pulse over current protection as well as closing a  
current control loop. A precision tachometer is also provided for imple-  
menting closed loop speed control. The TACH_OUT signal is a variable  
duty cycle, frequency output which can be used directly for digital con-  
trol or filtered to provide an analog feedback signal. Other features in-  
clude COAST, BRAKE, and DIR_IN commands along with a direction  
output, DIR_OUT.
