Integrated Quad Half H-Bridge with Power Supply, Embedded MCU, and LIN Serial Communication
The 908E625 is an integrated single package solution including 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 (ICG) module. The analog control die provides fully protected H-Bridge/high side outputs, voltage regulator, autonomous watchdog with cyclic wake-up, 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 mirror, door lock, and light-leveling applications.
