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), internal 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-leveling applications.
