MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA
33290

APPLICATIONS INFORMATION
INTRODUCTION
The 33290 is a serial link bus interface device conforming to
the ISO 9141 physical bus specification. The device was
designed for automotive environment usage compliant with On-
Board Diagnostic (OBD) requirements set forth by the California
Air Resources Board (CARB) using the ISO K line. The device
does not incorporate an ISO L line. It provides bi-directional
half-duplex communications interfacing from a microcontroller
to the communication bus. The 33290 incorporates circuitry to
interface the digital translations from 5.0 V microcontroller logic
levels to battery level logic and from battery level logic to 5.0 V
logic levels. The 33290 is built using Motorola’s SMARTMOS
process and is packaged in an 8-pin plastic SOIC.
FUNCTIONAL DESCRIPTION
The 33290 transforms 5.0 V microcontroller logic signals to
battery level logic signals and visa versa. The maximum data
rate is set by the fall time and the rise time. The fall time is set
by the output driver. The rise time is set by the bus capacitance
and the pull-up resistors on the bus. The fall time of the 33290
allows data rates up to 150 kbps using a 30 percent maximum
bit time transition value. The serial link interface will remain fully
functional over a battery voltage range of 6.0 to 18 V. The
device is parametrically specified over a dynamic V
BB
voltage
range of 8.0 to 18 V.
Required input levels from the microcontroller are ratio-
metric with the V
DD
voltage normally used to power the
microcontroller. This enhances the 33290’s ability to remain in
harmony with the R
X
and T
X
control input signals of the
microcontroller. The R
X
and T
X
control inputs are compatible
with standard 5.0 V CMOS circuitry. For fault-tolerant purposes
the T
X
input from the microcontroller has an internal passive
pull-up to V
DD
, while the CEN input has an internal passive pull-
down to ground.
A pull-up to battery is internally provided as well as an active
data pull-down. The internal active pull-down is current-limit-
protected against shorts to battery and further protected by
thermal shutdown. Typical applications have reverse battery
protection by the incorporation of an external 510
pull-up
resistor and diode to battery.
Reverse battery protection of the device is provided by using
a reverse battery blocking diode (“D” in the Simplified
Application Diagram on page 1). Battery line transient
protection of the device is provided for by using a 45 V zener
and a 500
resistor connected to the V
BB
source as shown in
the same diagram. Device ESD protection from the
communication lines exiting the module is through the use of
the capacitor connected to the V
BB
device pin and the capacitor
used in conjunction with the 27 V zener connected to the ISO
pin.
