MC33199 10 motorola analog ic device data introduction 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 adiagnosis system iso 9141o specification. this product description will detail the functionality of the device (see simplified application). the power supply and reference voltage generator will be discussed followed by the path functions between mcu, k and l lines. a dedicated paragraph will discuss the special functionality of the i1 pin in it's ability to accommodiate high baud rate transmissions. power supplies and reference voltage the device requires two power supplies to be used; a 5.0 v supply, v cc , which is normally connected to the mcu supply. the device v cc pin is capable of sinking typically 1.0 ma during normal operation. a v bat supply voltage, v s , is normally tied to the car's battery voltage. the v bat pin can sustain up to 40 v dc. care should be taken to provide any additional reverse battery and transient voltage protection in excess of 40 v. the voltage reference generator is supplied from both v cc and v bat pins. the voltage reference generator provides a reference voltage for the k and l line comparator thresholds. the reference voltage is dependant on the v bat voltage; it is linear in relation to the v bat voltage for all v bat voltages between 5.6 v and 18 v. below 5.6 v and over 18 v the reference voltage is clamped (see figure 11). the refout pin connects the reference voltage out externally making it available for other application needs. the refout pin is capable of supplying a current of 50 m a (see figure 12). path functions between mcu, k and l lines the path function from the mcu to the k line uses a driver to interface directly with the mcu through the txd pin. the txd pin is cmos compatible. this driver controls the onoff conduction of the power transistor. when the power transistor is on, it pulls the dia pin low. this pin is known as k line in the iso 9141 specification. the dia pin structure is open collector and requires an external pullup resistor for use. having an open collector without an internal pullup resistor allows several MC33199 to be connected to the k line while using a single pullup resistor for the system (see figure 6). in order to protect the dia pin against short circuits to v bat , the MC33199 incorporates an internal current limit (see figure 16) and thermal shutdown circuit. the current limit feature makes it possible for the device to drive a k line bus having a large parasitic capacitor value (see special functionality of i1 pin below). the path from the dia pin, or k line, to the mcu is done through a comparator. the comparator threshold voltage is connected to refink pin. it can be tied to the refout voltage if a v bat dependant threshold is required in the application. the second input of this comparator is connected internally to dia pin. the output of this comparator is available at the rxd output pin and normally connects to an mcu i/o port. rxd pin has a 2.0 k w internal pullup resistor. the path from the l line, used during a wakeup sequence of the transmission, to the mcu is done through a second comparator. the comparator threshold voltage is connected to refinl pin. the refink pin can be tied to the refout voltage if a v bat dependant threshold is required in the application. the second input of this comparator is internally connected to l pin. the output of this comparator is available on lo output pin, which is also an open collector structure. the lo pin is normally connected to an mcu i/o port. the dia and l pins can sustain up to 40 v dc. care should be taken to protect these pins from reverse battery and transient voltages exceeding 40 v. the dia and l pins both have internal pulldown current sources of typically 7.5 m a (see figure 14). the l line exhibits a 10 m a pulldown current. the dia pin has the same behavior when it is in aoffo state, that is when txd is at logic high level. special functionality of i1 pin the MC33199 has a unique feature which accommodates transmission baud rates of up to 200 k baud. in practice, the k line can be several meters long and have a large parasitic capacitance value. large parasitic capacitance values will slow down the low to high transition of the k line and limit the baud rate transmission. for the k line to go from low to high level, the parasitic capacitor must first be charged, and can only be charged through the pullup resistor. a low pullup resistor value would result in fast charge time of the capacitor but also large output currents to be supplied causing a high power dissipation in the driver. to avoid this problem, the MC33199 incorporates a dynamic current source which is temporarily activated at the low to high transition of the txd pin when the dia pin or k line switches from a low to high level (see figures 3 and 4). this current source is available at the i1 pin. the i1 pin has a typical current capability of 80 ma. it is activated for 4.0 m s (see figures 21 and 22) and is automatically disabled after this time. during this time it will charge the k line parasitic capacitor. this extra current will quickly increase the k line voltage up to v bat , resulting in a reduced rise time of the k line. with this feature, the MC33199 ensures baud rate transmission of up to 200 k baud. during high to low transitions of the k line, the parasitic capacitor of the line will be discharged by the output transistor of the dia pin. in this case, the total current may exceed the internal current limitation of the dia pin. if so, the current limit circuit will activate, limiting the discharge current to typically 60 ma (see figures 4 and 16). if a high baud rate is necessary, the i1 pin should be connected to the dia as shown in the typical application circuit shown in figure 5. the i1 pin can be left open, if the i1 functionality and high baud rate are not required for the application.
MC33199 11 motorola analog ic device data pin description pin 1: v cc power supply pin; typically 5.0 v and requiring less than 1.5 ma. pin 2: refinl input reference for c2 comparator. this input can be connected directly to refout with or without a resistor network or to an external reference. pin 3: refink input reference for c1 comparator. this input can be connected directly to refout with or without a resistor network or to an external reference. pin 4: lo output of c2 comparator and normally connected to a microcontroller i/o. if l input > (refinl + hyst/2); output lo is in high state. if l< (refinl hyst/2); output lo is in low state and the output transistor is aono. this pin is an open collector structure and requires a pullup resistor to be connected to v cc . output drive capability of this output is 5.0 ma. pin 5: rxd receive output normally connected to a microcontroller i/o. if dia input > (refinl + hyst/2); output lo is in high state. if dia < (refinl hyst/2); output lo is in low state and the output transistor is aono. this pin has an internal pullup resistor (typically 2.0 k w ) connected to v cc . drive capability of this output is 5.0 ma. pin 6: txd transmission input normally connected to a microcontroller i/o. this pin controls the dia output. if txd is high, the output dia transistor is in the aoffo state. if txd is low, the dia output transistor is aono. pin 9: dia input/output diagnosis bus line pin. this pin is an open collector structure and is protected against overcurrent and circuit shorts to v bat and v s . whenever the open collector transistor turns aono (txd low), the bus line is pulled to ground and the dia pin current is internally limited to nominal value of 60 ma. the internal power transistor incorporates a thermal shutdown circuit which forces the dia output aoffo in the event of an over temperature condition. the dia pin is also the c1 comparator input. it is protected against both positive and negative overvoltages by an internal 40 v zener diode. this pin exhibits a constant input current of 7.5 m a. pin 10: gnd ground reference for the entire device. pin 11: i1 bus source current pin. it is normally tied to dia pin and to the bus line. the current source i1 delivers a nominal current of 3.0 ma at static ahigho or alowo levels of txd. only during alowo to ahigho transitions, does this current increase to a higher value so as to charge the key line capacitor (cl < 4.0 nf) in a short time (see figures 3 and 4). pin 12: l input for c2 comparator. this pin is protected against both positive and negative overvoltage by a 40 v zener diode. this l line is a second independent input. it can be used for wake up sequence in iso diagnosis or as an additional input bus line. this pin exhibits a constant input current of 7.5 m a. pin 13: v s 12 v typical, or v bat supply pin for the device. this pin is protected against overvoltage transients. pin 14: refout internal reference voltage generator output pin. its value depends on v s (v bat) values. this output can be directly connected to refinl and refink, or through a resistor network. maximum current capability is 50 m a.
