Freescale Semiconductor
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 analog control IC. The HC08 includes flash memory, a
timer, enhanced serial communications interface (ESCI), a 10 bit
analog-to-digital converter (ADC), internal serial peripheral interface
(SPI), 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.
