Integrated Triple High-Side
Switch with Embedded MCU
and LIN Serial Communication
for Relay Drivers
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 three high-side outputs with diagnostic functions,
voltage regulator, watchdog, operational amplifier, 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-current motors
applications using relays (e.g., window lifts, fans, and sun roofs).
