Freescale Semiconductor Advance Information Document Number: MM908E425 Rev. 1.0, 8/2006 Integrated Quad Half H-Bridge with Power Supply, Embedded MCU, and LIN Serial Communication The 908E425 is an integrated single-package solution including a high-performance HC08 microcontroller with a SMARTMOS TM analog control IC. The HC08 includes Flash Memory, a timer, Enhanced Serial Communications Interface (ESCI), an Analog-toDigital Converter (ADC), Serial Peripheral Interface (SPI) (only internal), 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-levelling applications.
