Freescale Semiconductor Technical Data Document Number: MM908E624 Rev. 11.0, 4/2012 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 SMARTMOS analog control IC. The HC08 includes flash memory, a timer, enhanced serial communications 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). Features • High performance M68HC908EY16 core • 16 KB of on-chip flash memory, 512 B of RAM • Internal clock generator module • Two 16-bit, two-channel timers • 10-bit ADC • LIN physical layer interface • Low dropout voltage regulator • Three high side outputs • Two wake-up inputs • 16 microcontroller I/Os 908E624 908E624 HIGH SIDE SWITCH EW (Pb-FREE) SUFFIX 98ASA99294D 54-pin SOICW ORDERING INFORMATION Device (Add an R2 suffix for Tape and reel orders) Temperature Range (TA) Package MM908E624ACPEW MM908E624AYPEW -40°C to 85°C -40°C to 125°C 54 SOICW LIN Interface 5.0 V Microcontroller Ports LIN VREFH VDDA EVDD VCC VDD VREFL VSSA EVSS AGND GND VSP1 RXD PTE1/RXD RST RST_A IRQ IRQ_A PTD0/TACH0 PW/MIN PTA0-4 PTB1;3-7 PTC2-4 PTD1/TACH1 VSP HS3 L1 L2 HS1 HS2 +E WDCONF OUT -E VBAT M To Microcontroller A/D Channel Figure 1. 908E624 Simplified Application Diagram *This document contains certain information on a product under development.
