Freescale Semiconductor
Technical Data
MM908E622
Rev 1.0, 09/2005
Integrated Quad Half-Bridge,
Triple High-Side and EC Glass
Driver with Embedded MCU and
LIN for High End Mirror
The 908E622 is an integrated single-package solution that
includes 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 module. The analog
control die provides four half-bridge and three high-side outputs with
diagnostic functions, an EC glass driver circuit, a Hall-Effect sensor
input, analog inputs, voltage regulator, window watchdog, 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 high-end mirrors.
