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), a 10 bit
analog-to-digital converter (ADC), serial peripheral interface (SPI)
(only internal), and an internal clock generator module (ICG). 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.
