DESCRIPTION
The IC is a PWM EC brushless motor driver/controller to imple-
ment a motor regulator together with n-channel power FET B

-
configuration and a μC The programmability of parameters (e.g.
threshold values of over current, over temperature, motor fail-
ures, 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.
The device works in typical motor regulator systems as physical
interface between a μC or a special controller hardware and the
power FET-motor load configuration. The user has the complete
control over the logical behaviour by software implementation in
the μC. In this way all control/regulation strategies of the motor
can be realised by software development.
