Technical Data
Integrated Quad Half-Bridge
and Triple High-Side with
Embedded MCU and LIN for
High End Mirror
The 908E621 is an integrated single-package solution that
includes 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 module. The analog
control die provides four half-bridge and three high-side outputs with
diagnostic functions, 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.
