MM908E625
Rev 4.0, 09/2005
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.
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.
