Document Number: MM908E622 Freescale Semiconductor Rev. 3.0, 4/2012 Technical Data Integrated Quad Half-bridge, 908E622 Triple High Side and EC Glass Driver with Embedded MCU and LIN for High End Mirror QUAD HALF-BRIDGE, TRIPLE HIGH SIDE SWITCH AND EC GLASS CIRCUITRY WITH EMBEDDED MCU AND LIN The 908E622 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), a 10 bit analog-to-digital converter (ADC), internal serial peripheral interface (SPI), and an internal clock generator module (ICG). The analog control die provides four half- bridge and three high side outputs with diagnostic functions, an EC glass driver circuit, a Hall effect sensor input, analog inputs, voltage regulator, window watchdog, 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 98ASA10712D It is well-suited for the control of automotive high-end mirrors. 54-PIN SOICW-EP Features High performance M68HC908EY16 core 16 KB of on-chip flash memory, 512 B of RAM ORDERING INFORMATION Two 16-bit, two-channel timers LIN physical layer interface Device Temperature (Add an R2 suffix for Package Autonomous MCU watchdog / MCU supervision Range (T ) A Tape and reel orders) One analog input with switchable current source Four low R half-bridge outputs DS(ON) MM908E622ACPEK - 40 to 85 C 54 SOICW-EP Three low R high side outputs DS(ON) EC glass driver circuitry Wake-up and 2 or 3-pin Hall effect sensor input 12 microcontroller I / Os >22 F 100 nF VSP1:8 LIN Wake-up Input L0 VDDA/VREFH EVDD 4.7 F HB1 VDD M 100 nF VSSA/VREFL HB2 EVSS 4 x Half-bridge Outputs M VSS HB3 908E622 RST A M RST HB4 High Side Output 1 IRQ A HS1 IRQ High Side Output 2 HS2 PTA0/BD0 HS3 High Side Output 3 PTA1/KBD1 C PortA PTA2/KBD2 High Side Output 1 HS1 PTA3/KBD3 PTA4/KBD4 ECR EC - Glass Control PTB3/AD3 EC C PortB PTB4/AD4 HVDD Switched 5.0 V Output PTB5/AD5 A0 Analog Input with Current Source PTC2/MCLK Analog Input Current Source Trim A0CST C PortC PTC3/OSC2 PTC4/OSC1 Two 3-pin Hall Sensor Input H0 PTD0/TACH0 Internally Connected C PortD TESTMODE Pull to GND for User Mode PTD1/TACH1 C PortE PTE1/RXD GND 1:4 EP Internally Connected Figure 1. 908E622 Simplified Application Diagram Freescale Semiconductor, Inc. reserves the right to change the detail specifications, as may be required, to permit improvements in the design of its products.
