DESCRIPTION
The IC is a PWM EC brushless motor driver/controller to implement a motor regulator together with n-channel power FET B6- configuration and a µC The programmability of parameters (e.g. threshold values of over current, over temperature, motor failures, EMC conditions, etc.) can be used to drive motors in a widely different range. These programmability features and the driver channel control inputs and allow this chip to act in general motor regulator applications, too. The special programmable switching technology (pendingpatent) enables an excellent EMC behavior.
