Product Information

Freescale Semiconductor Technical Data MM908E624 Internal Rev 4.0, 12/2004 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, 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).
