All typical values are at 25°C and supply voltages of VCC = 5 V and VIO = 3.3 V.
The VCC supply is not needed during standby mode so in the application ICC in standby mode may be zero. If the VCC supply remains,
then ICC is per specification with VCC.

The TXD dominant time out (t(DOM)) disables the driver of the transceiver once the TXD has been dominant longer than t(DOM), which
releases the bus lines to recessive, preventing a local failure from locking the bus dominant. The driver may only transmit dominant
again after TXD has been returned HIGH (recessive). While this protects the bus from local faults, locking the bus dominant, it limits the
minimum data rate possible. The CAN protocol allows a maximum of eleven successive dominant bits (on TXD) for the worst case,
where five successive dominant bits are followed immediately by an error frame. This, along with the t(DOM) minimum, limits the
minimum bit rate. The minimum bit rate may be calculated by: Minimum Bit Rate = 11/ t(DOM) = 11 bits / 300 µs = 37 kbps

HVDA54x-5 devices: VIO is internally connected to VCC
Figure 14. HVDA54x-5 Functional Block Diagram
8.3 Feature Description
8.3.1 Digital Inputs and Outputs
The HVDA54x devices have an I/O supply voltage input pin (VIO) to ratiometrically level shift the digital logic input
and output levels with respect to VIO for compatibility with protocol controllers having I/O supply voltages between
3 V and 5.33 V.
The HVDA54x-5 devices have a single VCC supply (5 V). The digital logic input and output levels for these
devices are with respect to VCC for compatibility with protocol controllers having I/O supply voltages between
4.68 V and 5.33 V.
8.3.2 TXD Dominant State Time Out
During normal mode, the only mode where the CAN driver is active, the TXD dominant time out circuit prevents
the transceiver from blocking network communication in event of a hardware or software failure where TXD is
held dominant longer than the time-out period t(DOM). The dominant time out circuit is triggered by a falling edge
on TXD. If no rising edge is seen before the time out constant of the circuit expires (t(DOM)) the CAN bus driver is
disabled freeing the bus for communication between other network nodes. The CAN driver is reactivated when a
recessive signal is seen on TXD pin, thus clearing the dominant state time out. The CAN bus pins is biased to
recessive level during a TXD dominant state time out.

Feature Description (continued)
NOTE
The maximum dominant TXD time allowed by the TXD Dominant state time out limits the
minimum possible data rate of the device. The CAN protocol allows a maximum of eleven
successive dominant bits (on TXD) for the worst case, where five successive dominant
bits are followed immediately by an error frame. This, along with the t(DOM) minimum, limits
the minimum bit rate.
The minimum bit rate may be calculated in Equation 1:
Minimum Bit Rate = 11/t(DOM)
(1)
8.3.3 Thermal Shutdown
If the junction temperature of the device exceeds the thermal shut down threshold the device will turn off the
CAN driver circuits. This condition is cleared once the temperature drops below the thermal shut down
temperature of the device. The CAN bus pins will be biased to recessive level during a thermal shutdown.
8.3.4 Undervoltage Lockout and Unpowered Device
Both of the supply pins have undervoltage detection which place the device in forced standby mode to protect
the bus during an undervoltage event on either the VCC or VIO supply pins. If VIO is undervoltage the RXD pin is
tri-stated and the device does not pass any wake-up signals from the bus to the RXD pin. Since the device is
placed into forced standby mode the CAN bus pins have a common mode bias to ground protecting the CAN
network, see Figure 15 and Figure 16.
The device is designed to be an ideal passive load to the CAN bus if it is unpowered. The bus pins (CANH,
CANL) have extremely low leakage currents when the device is unpowered so they will not load down the bus
but rather be no load. This is critical, especially if some nodes of the network will be unpowered while the rest of
the network remains in operation.
NOTE
Once an undervoltage condition is cleared and the VCC and VIO have returned to valid
levels the device will typically need 300 µs to transition to normal operation.

When VIO is undervoltage, the device is forced into standby mode with respect to the CAN bus since there is not a valid digital reference
to determine the digital I/O states or power the wake-up receiver.

8.3.5 Floating Pins
The device has integrated pullup and pulldowns on critical pins to place the device into known states if the pins
float. The TXD pin is pulled up to VIO to force a recessive input level if the pin floats. The STB is pulled up to the
IO supply pin, VIO(HVDA540 and HVDA541), or VCC (HVDA540-5 and HVDA541-5) to force the device in
standby mode (low power) if the pin floats. The S pin is pulled down to GND to force the device into normal
mode if the pin floats (HVDA542 and HVDA542-5).
8.3.6 CAN Bus Short-Circuit Current Limiting
The device has several protection features that limit the short circuit current when a CAN bus line is shorted.
These include CAN driver current limiting (dominant and recessive) and TXD dominant state time out to prevent
continuously driving dominant. During CAN communication the bus switches between dominant and recessive
states, thus the short circuit current may be viewed either as the current during each bus state or as a DC
average current. For system current and power considerations in termination resistance and common mode
choke ratings the average short circuit current should be used. The device has TXD dominant state time out
which prevents permanently having the higher short circuit current of dominant state. The CAN protocol also has
forced state changes and recessive bits such as bit stuffing, control fields, and interframe space. These ensure
there is a minimum recessive amount of time on the bus even if the data field contains a high percentage of
dominant bits.
NOTE
The short circuit current of the bus depends on the ratio of recessive to dominant bits and
their respective short circuit currents.
The average short circuit current may be calculated by Equation 2:
IOS(AVG) = %Transmit * [(%REC_Bits * IOS(SS)_REC) + (%DOM_Bits * IOS(SS)_DOM)] + [%Receive * IOS(SS)_REC]
where
•
•
•
•
•
•
•
IOS(AVG) is the average short circuit current,
%Transmit is the percentage the node is transmitting CAN messages,
%Receive is the percentage the node is receiving CAN messages,
%REC_Bits is the percentage of recessive bits in the transmitted CAN messages,
%DOM_Bits is the percentage of dominant bits in the transmitted CAN messages,
IOS(SS)_REC is the recessive steady state short circuit current
and IOS(SS)_DOM is the dominant steady-state short circuit current.

8.4 Device Functional Modes
The device has two main operating modes: normal mode (all devices) and standby mode (HVDA540 / 541) or
silent mode (HVDA542). Operating mode selection is made through the STB (HVDA540 / 541) or the S
(HVDA542) input pin.

8.4.1 Bus States by Mode
The CAN bus has three valid states during powered operation depending on the mode of the device. In normal
mode the bus may be dominant (logic LOW) where the bus lines are driven differentially apart or recessive (logic
HIGH) where the bus lines are biased to VCC/2 via the high-ohmic internal input resistors RIN of the receiver. The
third state is low power standby mode where the bus lines will be biased to GND via the high-ohmic internal input
resistors RIN of the receiver.

8.4.2 Normal Mode
This is the normal operating mode of the device. It is selected by setting STB or S low. The CAN driver and
receiver are fully operational and CAN communication is bidirectional. The driver is translating a digital input on
TXD to a differential output on CANH and CANL. The receiver is translating the differential signal from CANH
and CANL to a digital output on RXD. In recessive state the CAN bus pins (CANH and CANL) are biased to
0.5 × VCC. In dominant state the bus pins are driven differentially apart. Logic high is equivalent to recessive on
the bus and logic low is equivalent to a dominant (differential) signal on the bus.
8.4.3 Standby Mode (HVDA540)
This is the low power mode of the device. It is selected by setting STB high. The CAN driver and receiver are
turned off and bidirectional CAN communication is not possible. There is no wake up capability in the HVDA540,
the RXD pin will remain recessive (high) while the device is in standby mode. This state is supplied via the VIO
supply, thus the VCC (5V) supply may be turned off for additional power savings at the system level. The local
protocol controller (MCU) should reactivate the device to normal mode to enable communication via the CAN
bus. The 5 V (VCC) supply needs to be reactivated by the local protocol controller to resume normal mode if it
has been turned off for low-power standby operation. The CAN bus pins are weakly pulled to GND, see
Figure 15 and Figure 16.
8.4.4 Standby Mode With RXD Wake Up-Request (HVDA541)
This is the low power mode of the device. It is selected by setting STB high. The CAN driver and main receiver
are turned off and bidirectional CAN communication is not possible. The low power receiver and bus monitor,
both supplied via the VIO supply, are enabled to allow for RXD wake up requests via the CAN bus. The VCC (5V)
supply may be turned off for additional power savings at the system level. A wake up request will be output to
RXD (driven low) for any dominant bus transmissions longer than the filter time tBUS. The local protocol controller
(MCU) should monitor RXD for transitions and then reactivate the device to normal mode based on the wake up
request. The 5 V (VCC) supply needs to be reactivated by the local protocol controller to resume normal mode if it
has been turned off for low-power standby operation. The CAN bus pins are weakly pulled to GND, see
Figure 15 and Figure 16.
8.4.4.1 RXD Wake Up Request Lock Out for Bus Stuck Dominant Fault (HVDA541)
If the bus has a fault condition where it is stuck dominant while the HVDA541 is placed into standby mode via the
STB pin, the device locks out the RXD wake up request until the fault has been removed to prevent false wake
up signals in the system.
