Integrated Quad Half-Bridge,
Triple High-Side and EC Glass
Driver with Embedded MCU and
LIN for High End Mirror
includes a high-performance HC08 microcontroller with a
SMARTMOS
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.
application performance adjustments and space-saving PCB design.
It is well suited for the control of automotive high-end mirrors.
