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
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 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).
Features
• High performance M68HC908EY16 core
• 16 KB of on-chip flash memory, 512 B of RAM
• Internal clock generator module
• Two 16-bit, two-channel timers
• 10-bit ADC
• LIN physical layer interface
• Low dropout voltage regulator
• Three high side outputs
• Two wake-up inputs
• 16 microcontroller I/Os
