Analog, Mixed Signal and Power Management MM908E621 Integrated Quad Half-bridge and Triple High Side with Embedded MCU and LIN for High End Mirror Applications MM908E621 Simplified Application Diagram • Automotive • Robotics • Small DC Motor Control • Lamp / LED Control • Marine Systems Overview The 908E621 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), a 10 bit analog-to-digital converter (ADC), internal serial peripheral interface (SPI), and an internal clock generator module (ICG). The analog control die provides four halfbridge and three high side outputs with diagnostic functions, a Hall effect sensor input, analog inputs, voltage regulator, window watchdog, 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 end mirrors.
