Overview: Freescale Semiconductor Technical Data Document Number: MM908E624 Rev. 11.0, 4/2012 Integrated Triple High Side Switch with Embedded MCU and LIN Serial munication 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 munications interface (ESCI), an analogto-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).
