General Description
The 3-phase motor controller is intended to operate dif-
fent kinds of 3-phase stepper motors or BLDC motors-
for various applications.
The communication complies to LIN rev. 2.x or 1.3 with
a baud rate of up to 19.2kBaud.
The internal microcontroller allows high flexibility of
protocol handling and motor control. It can be ROM
mask programmed with customer's firmware or a vari-
ant with FLASH memory can be used.
On the PCB besides the IC only few passive components
are required for supply filtering.
Equipped with a suitable application software, the
IC is capable to fulfill the requirements of the stand-
ard climate control actuator as described in the docu-
ment "Lastenheft Klima-Standardaktuator mit LIN-Bus-
Schnittstelle 2.x".
