Integrated Triple High Side
Switch with Embedded MCU
and LIN Serial Communication
for Relay Drivers
The 908E624 is an integrated single-package solution that
includes a high-performance HC08 microcontroller with a
SMARTMOSTM 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 three high side outputs with diagnostic functions,
voltage regulator, watchdog, current sense operational amplifier, 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-current motors
applications using relays (e.g., window lifts, fans, and sun roofs).
