Technical Data

Integrated Stepper Motor Driver

with Embedded MCU and LIN

Serial Communication

908E626

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.

STEPPER MOTOR DRIVER

WITH EMBEDDED MCU AND LIN

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.
