Rev 3.0, 09/2004
Advance Information
Integrated Quad Half H-Bridge with
Power Supply, Embedded MCU, and
LIN Serial Communication
The 908E625 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), and an internal clock generator (ICG) module. The analog
control die provides fully protected H-Bridge/high-side outputs, voltage
regulator, autonomous watchdog with cyclic wake-up, 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 mirror, door lock, and light-levelling
applications.
