Integrated Stepper Motor Driver
with Embedded MCU and LIN
Serial Communication
The 908E626 is an integrated single package solution that includes
a high performance HC08 microcontroller with a SMARTMOS analog
control IC. The HC08 includes flash memory, a timer, enhanced serial
communications interface (ESCI), an analog-to-digital converter
(ADC), internal serial peripheral interface (SPI), and an internal clock
generator (ICG) module. The analog control die provides fully
protected H-Bridge outputs, voltage regulator, autonomous watchdog,
and local interconnect network (LIN) physical layer.
The single package solution, together with LIN, provides optimal
application performance adjustments and space-saving PCB design. It
is well-suited for the control of automotive stepper applications like
climate control and light-leveling.
