LS7290 Description
The LS7290 generates Phase Drive outputs a nd PWM output s for controlling twophase Bipolar Motors or four-phase Un ipolar Motors, respectively. The LS7290 contains a mod e controlled loo k-up table for generating the motor duty cycle drive sequences. There are four outputs which are used to drive two H-Bridges for the two motor windings in the Bipolar motor or the fo ur driver transistors for the t wo ce ntertapped...
