Advance Information
908E626
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
TM
analog control IC.
The HC08 includes flash memory, a timer, enhanced serial communications
interface (ESCI), an analog-to-digital converter (ADC), serial peripheral
interface (SPI) (only internal), 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-levelling.
