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 SMARTMOS 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.
