Document Number: MM908E425
Rev. 1.0, 8/2006
Integrated Quad Half H-Bridge
with Power Supply, Embedded
MCU, and LIN Serial
Communication
The 908E425 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.

Notes
1. Transient capability for pulses with a time of t < 0.5 sec.
2. ESD voltage testing is performed in accordance with the Human Body Model (CZAP = 100 pF, RZAP = 1500 ), ESD voltage testing is
performed in accordance with the Machine Model (CZAP =200 pF, RZAP = 0 , ESD voltage testing is performed in accordance with
Charge Device Model, robotic (CZAP =4.0 pF).
3. The limiting factor is junction temperature, taking into account the power dissipation, thermal resistance, and heat sinking.
4. The temperature of analog and MCU die is strongly linked via the package, but can differ in dynamic load conditions, usually because
of higher power dissipation on the analog die. The analog die temperature must not exceed 150°C under these conditions.
5. Pin soldering temperature is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause
malfunction or permanent damage to the device.
