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

Definition
5V typical power supply pin. typical supply current is less than 1.5mA
Input reference for C2 comparator.
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.
Internal reference voltage generator output pin.
