Advance Information

Integrated Quad Half H-Bridge

with Power Supply, Embedded

MCU, and LIN Serial

908E425

Communication

H-BRIDGE POWER SUPPLY WITH

EMBEDDED MCU AND LIN

The 908E425 is an integrated single-package solution including 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) (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.
