DESCRIPTION
Power drivers are Integrated DMOS transistors and feature fast recirculating diodes as an integral BLOCK DIAGRAM SPINDLE DRIVER ADVANCE DATA PLCC21+7 ORDERING NUMBER: L6232B part of their structure. All necessary circuitry to perform PWM and linear motor speed control is included. A central charge pump is utilized to drive the upper DMOS transistors, and also to power the braking function. The L6232B is packaged in PLCC28. March 1993 1/10 This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
