Document Number: MM908E625 Freescale Semiconductor Rev 10, 04/2012 Technical Data Integrated Quad Half H-Bridge 908E625 with Power Supply, Embedded MCU, and LIN Serial Communication H-BRIDGE POWER SUPPLY WITH EMBEDDED MCU AND LIN The 908E625 is an integrated single package solution including a high performance HC08 microcontroller with a SMARTMOS analog control IC. The HC08 includes flash memory, a timer, enhanced serial communications interface (ESCI), an analog-to-digital converter (ADC), internal serial peripheral interface (SPI), 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. EK SUFFIX It is well-suited for the control of automotive mirror, door lock, and 98ARL10519D light-leveling applications. 54-PIN SOICW-EP Features High-performance M68HC908EY16 core 16 KB of on-chip flash memory & 512 B of RAM ORDERING INFORMATION Internal clock generation module Device Two 16-bit, two-channel timers Temperature (Add an R2 suffix for Tape Package 10-bit ADC Range (T) A and reel orders) LIN physical layer 54 SOICW Autonomous watchdog with cyclic wake-up MM908E625ACPEK -40 to 85 C EP Three two-pin Hall effect sensor input ports One analog input with switchable current source Four low R half-bridge outputs DS(ON) One low R high side output DS(ON) 13 micro controller I/Os 908E625 LIN VSP1:3 HB1 VREFH Four Half-bridges VDDA M M M Controlling 3 Loads EVDD HB2 VDD HB3 VREFL HB4 VSSA High Side Output HS EVSS VSS HVDD Switchable Internal V Output RST A DD RST H1 IRQ A H2 Three 2-pin Hall-effect Sensor Inputs IRQ SS H3 PTB1/AD1 RXD PTE1/RXD PA1 Analog Input with Current Source PTD1/TACH1 PORTA I/Os FGEN PORTB I/Os Microcontroller Ports BEMF PORTC I/Os PTD0/TACH0/BEMF GND 1:2 EP Figure 1. 908E625 Simplified Application Diagram * This document contains information on a new product.
