Analog, Mixed Signal and Power Management MM908E624 Integrated Triple High Side Switch with Embedded MCU and LIN Serial Communication for Relay Drivers Applications • • • • • Automotive Robotics DC Motor Control Relay Driver Applications Marine Systems MM908E624 Simplified Application Diagram 908E624 VBAT LIN Interface 5.0 V 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).
