Brushless DC Motor Controller

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 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.
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.
