Document Number: MM908E625
Rev 7.0, 9/2010
Integrated Quad Half H-Bridge
with Power Supply, Embedded
MCU, and LIN Serial
Communication
The 908E625 is an integrated single-package solution including a
high-performance HC08 microcontroller with a SMARTMOSTM 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/high-side outputs, voltage regulator,
autonomous watchdog with cyclic wake-up, and Local Interconnect
Network (LIN) physical layer.
908E625
H-BRIDGE POWER SUPPLY 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 mirror, door lock, and
light-levelling applications.
