1 / 40 page  Document Number: MM908E624 Rev. 9.0, 9/2010 Freescale Semiconductor Advance Information * This document contains certain information on a new product. Specifications and information herein are subject to change without notice. © Freescale Semiconductor, Inc., 2010. All rights reserved. Integrated Triple High Side Switch with Embedded MCU and LIN Serial Communication for Relay Drivers The 908E624 is an integrated single-package solution that includes a high-performance HC08 microcontroller with a SMARTMOSTM analog control IC. The HC08 includes flash memory, a timer, enhanced serial communications interface (ESCI), an analog-to-digital converter (ADC), serial peripheral interface (SPI) (only internal), 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).
