Automotive ISO 9141 Serial Link Driver

www.DataSheet4U.com Freescale Semiconductor Technical Data Document Number: MC33199 Rev. 4.0, 10/2006 Automotive ISO 9141 Serial Link Driver The MC33199 is a serial interface circuit used in diagnostic applications. It is the interface between the microcontroller and the special K and L lines of the ISO diagnostic port. The MC33199 has been designed to meet the «Diagnosis System ISO9141» specification. The device has a bi-directional bus K line driver, fully protected against short circuits and over temperature. It also includes the L line receiver, used during the wake up sequence in the ISO transmission. The MC33199 has a unique feature which allow transmission Baud rate up to 200kBaud. Features • Electrically Compatible with Specification “Diagnosis System ISO9141” • Transmission speed up to 200kBaud • Internal Voltage Reference Generator for Line Comparator Thresholds • TXD, RXD and LO pins are 5V CMOS Compatible • High Current Capability of DIA pin (K line) • Short Circuit Protection for the K Line Input • Over Temperature Shutdown with Hysteresis • Large Operating Range of Driver Supply Voltage • Large Operating Temperature Range • ESD Protected pins • Pb-Free Packaging Designated by Suffix Code EF 33199 LIN, ISO-9141 J-1850 PHYSICAL INTERFACES D SUFFIX EF SUFFIX (PB-FREE) PLASTIC PACKAGE 98ASB42565B 14 PIN SOIC ORDERING INFORMATION Device MC33199D MCZ33199EF/R2 Temperature Range (TA) -40°C to 125°C Package 14 SOIC VBAT VDD 33199 VDD VCC VS MCU I/O LO RXD TXD L I1 DIA ISO L-LINE SCIRXD SCITXD (BUS) ISO K-LINE GND Figure 1.

Input reference for C1 comparator. This pin control Sleep Mode, Transmit Level, and Speed. It has a weak pulldown. Open drain output of the data on BUS. A recessive bus = a logic [1], a dominant bus = logic [0]. An external pullup is required. Data input here will appear on the BUS pin. A logic [0] will assert the bus, a logic [1] will make the bus go to the recessive state. No internal connection to these pins. Provides a battery-level logic signal. Electrical Common Ground and Heat removal. A good thermal path will also reduce the die temperature. Power input. An external diode is needed for reverse battery protection. The external bus load resistor connects here to prevent bus pullup in the event of loss of module ground. This pin connects to the bus through external components.
