Automotive ISO 9141
Serial Link Driver
The MC33199D 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 MC33199D has been
designed to meet the âDiagnosis System ISO 9141â specification.
The device has a biâdirectional 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 allows transmission baud rate
up to 200 k baud.
⢠Electrically Compatible with Specification âDiagnosis System ISO 9141â
⢠Transmission Speed Up to 200 k Baud
⢠Internal Voltage Reference Generator for Line Comparator Thresholds
⢠TXD, RXD and LO Pins are 5.0 V 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
⢠Full Operating Temperature Range
⢠ESD Protected Pins
