FEATURES
DESCRIPTION
The AU5783 is a line transceiver being primarily intended for
in-vehicle multiplex applications. It provides interfacing between a
J1850 link controller and the physical bus wire. The device supports
the SAE/J1850 VPWM standard with a nominal bus speed of 10.4
kbit/s. For data upload and download purposes the 4X transmission
mode is supported with a nominal bus speed of 41.6 kbit/s. The
AU5783 provides protection against loss of ground conditions, thus
ensuring the network will be operational in case of an electronic
control unit loosing connection to ground potential. Low power
operation is supported through provision of a sleep mode with very
low power consumption. In addition an external voltage regulator
can be turned off via the AU5783 transceiver to further reduce the
overall power consumption. The voltage regulator will be activated
again upon detection of bus activity or upon a local wake-up event.

FUNCTIONAL DESCRIPTION
The AU5783 is an integrated line transceiver IC that interfaces an
SAE/J1850 protocol controller IC to the vehicle’s multiplex bus line.
It is primarily intended for automotive “Class B” multiplexing
applications in passenger cars using VPW (Variable Pulse Width)
modulated signals with a nominal transmission speed of 10.4 kbit/s.
The device provides transmit and receive capability as well as
protection to a J1850 electronic module.

A J1850 link controller feeds the transmit data stream to the
transceiver’s TX input. The AU5783 transceiver waveshapes the TX
data input signal so as to minimize electromagnetic emission. The
bus output signal features controlled rise & fall characteristic
including rounded shape. A resistance being connected to the R/F
control input sets the bus output slew rate.

outputs an active state. This output ensures the J1850 network will
not be affected by a potential loss of ground condition at an
individual electronic control unit.

The AU5783 includes a bus receiver with filter function to minimize
susceptibility against interference. The logic state of the J1850 bus
signal is indicated at the RX output being connected to the J1850

DESCRIPTION
The AU5783 also provides advanced low-power modes to help
minimize ignition-off power consumption of an electronic control unit.
The bus receiver function is kept alive in the low-power modes. If an
active state is being detected on the bus line this will be indicated
via the RX output. By default the AU5783 enters the low-power
standby mode when the mode control inputs NSTB and 4X/LOOP
are not driven.

Ignition-off current draw can be reduced further by turning off the
voltage regulator being typically provided in an electronic control
unit. This is supported by the activity indication function of the
AU5783. In this application the activity indication flag INH will control
external devices such as a voltage regulator. To turn-off the INH flag
and thus the voltage regulator, the go to sleep command needs to
be applied to the Network Standby power control input,
e.g., NSTB = 0. The INH output is turned off after the sleep time-out
period thereby, reducing the power consumption of an electronic
control unit to an extremely low level.

The activity indication flag INH will be turned on again upon
detection of a remote wake-up condition (i.e. bus activity) or upon
detection of a local wake-up condition or a respective command
from the microcontroller. A local wake-up condition is detected when
an edge occurs at the wake-up input LWAKE. The INH flag will also
be turned on upon detection of a high input level at the mode control
input NSTB. Activation of the INH output enables external devices
e.g., a voltage regulator. This condition will power-up logic devices
e.g., a microcontroller in order to perform appropriate action,
e.g., activation of the AU5783 and the J1850 network.

The AU5783 provides a high-speed data transmission mode where
the bus output waveshape function is disabled. In this mode transmit
signals are output as fast as possible thus allowing higher data
rates, e.g. the so-called 4X mode with 41.6 kbit/s nominal speed.
The AU5783 also provides a loop-back mode for diagnostic
purpose, e.g. self-test of an electronic control unit. In loop-back
mode the bus transmit and receive functions are disabled thus

voltage as well as typical automotive transients and electrostatic
discharge. In addition, an over-temperature shutdown function with
hysteresis is incorporated which protects the device under network
fault conditions. In case of the die temperature reaching the trip
point, the AU5783 will latch-off the transceiver function. The device
is reset on the first rising edge on the TX input after a decrease in
the junction temperature.
The AU5783 features special robustness at its BAT and BUS pins
hence the device is well protected for applications in the automotive
environment. Specifically the BAT input is protected against 40V
load dump and jump start condition. The BUS output is protected
against wiring fault conditions e.g. short circuit to ground and battery

NOTES:
1. After power-on, the AU5783 enters standby mode since the input pins NSTB and 4X/LOOP are assumed to be floating. In standby mode the
voltage regulator is enabled via the INH output, and therefore power is supplied to the microcontroller. When the microcontroller begins
operation it will normally set the control inputs NSTB high and 4X/LOOP to low state in order to start normal operation of the AU5783.
2. RX outputs the bus state. If the bus level is below the receiver threshold (i.e., all transmitters passive), then RX will be high. Otherwise, if the
bus level is above the receiver threshold (i.e., at least one transmitter is active), then RX will be low.
3. INH is turned off after a time-out period.
4. For entering the sleep mode (e.g., to deactivate INH), the “Go To Sleep” command needs to be applied. The “Go To Sleep” command is a
high-to-low transition on the NSTB input. When the “Go To Sleep” command is present, the INH flag is deactivated. This signal can be used
to turn-off the voltage regulator of an electronic module. After the voltage regulator is turned off the microcontroller is no longer supplied and
the NSTB input will be floating. The INH output will be set again upon detection of bus activity or occurrence of a local wake-up event.
5. In standby and sleep mode, the detection of a wake-up condition (e.g., high level on BUS) will be signalled on the output RX.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
Application information — Applications that are described herein for any of these products are for illustrative purposes only. Philips
Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or
modification.
