Overview
The 908E624 is an integrated single
package solution that includes a highperformance HC08 microcontroller with a
SMARTMOS analog control IC. The HC08
includes flash memory, a timer, enhanced
serial communications interface (ESCI),
an analog-to-digital converter (ADC),
internal serial peripheral interface (SPI),
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 spacesaving 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).
