voltage- or current-mode configurations. The  
oscillator 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  
demanding two-quadrant applications.

Trimmed Precision Reference  
Precision Oscillator  
The device includes a differential current-sense  
amplifier and absolute-value circuit which provide  
an accurate reconstruction of motor current,  
useful for pulse-by-pulse overcurrent protection,  
as well as closing a current control loop. A  
precision tachometer is also provided for  
implementing closed-loop speed control. The  
TACH_OUT signal is a variable duty-cycle,  
frequency output, which can be used directly for  
digital control or filtered to provide an analog  
feedback signal. Other features include COAST,  
BRAKE, and DIR_IN commands, along with a  
direction output, DIR_OUT.

DESCRIPTION  
The UCC3626 motor controller device combines  
many of the functions required to design a  
high-performance, two- or four-quadrant, three-  
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 motor control in either
