THERMAL PROTECTION

DEVICE OVERVIEW
The thermal protection circuit monitors the die
temperature and is able to shut down the LIN
transmitter.
The MCP2003/4 provides a physical interface between
a microcontroller and a LIN bus. This device will
translate the CMOS/TTL logic levels to LIN logic level,
and vice versa. It is intended for automotive and
industrial applications with serial bus speeds up to
20 Kbaud.
There are two causes for a thermal overload. A thermal
shut down can be triggered by either, or both, of the
following thermal overload conditions.
LIN specification 2.1 requires that the transceiver of all
nodes in the system is connected via the LIN pin, refer-
enced to ground and with a maximum external
termination resistance of 510 from LIN bus to battery
supply. The 510 corresponds to 1 master and
15 slave nodes.
• LIN bus output overload
• Increase in die temperature due to increase in
environment temperature
Driving the TXD and checking the RXD pin makes it pos-
sible to determine whether there is a bus contention
(Rx = low, Tx = high) or a thermal overload condition
(Rx = high, Tx = low). After a thermal overload event,
the device will automatically recover once the die tem-
perature has fallen below the recovery temperature
threshold. See Figure 1-1.
The VREN pin can be used to drive the logic input of an
external voltage regulator. This pin is high in all modes
except for Power Down mode.

An external 43V transient suppressor (TVS) diode,
between VBB and ground, with a 50 transient
protection resistor (RTP) in series with the battery
supply and the VBB pin serve to protect the device from
power transients (see Example 1-1) and ESD events.
While this protection is optional, it is considered good
engineering practice.

ESD PROTECTION
For component-level ESD ratings, please refer to the
maximum operation specifications.
1.2.2
GROUND LOSS PROTECTION
The LIN Bus specification states that the LIN pin must
transition to the recessive state when ground is
disconnected. Therefore, a loss of ground effectively
forces the LIN line to a high-impedance level.

MCP2003/4
the TXD pin is held low when CS goes high, the device
will transition to Transmitter Off mode instead of
Operation mode.
1.3
Modes of Operation
For an overview of all operational modes, refer to
Table 1-1.
1.3.3
OPERATION MODE
1.3.1
POWER-DOWN MODE
In this mode, all internal modules are operational.
In Power Down mode, the transmitter and VREN are
both off. Only the receiver section and the wake-up
circuits are operational. This is the lowest power
mode.
The MCP2003/4 will go into the Power Down mode on
the falling edge of CS. The MCP2003/4 will enter
Transmitter Off mode in the event of a Fault condition.
These include: thermal overload, bus contention and
TXD timer expiration.
On bus activity (e.g. a BREAK character), CS going to
a high level, or on a falling edge on WAKE, the device
will immediately enter Ready mode. If CS is held high
as the device transitions from Power Down to Ready
mode, the device will transition to Operation mode as
soon as internal voltages stabilize.
The MCP2004 device can also enter Transmitter Off
mode if the FAULT/TXE pin is pulled low
1.3.4
TRANSMITTER OFF MODE
Transmitter Off mode is reached whenever the
transmitter is disabled either due to a Fault condition or
pulling the nFAULT/TXE pin low on the MCP2004. The
fault conditions include: thermal overload, bus
contention or TXD timer expiration.
Note:
Bus activity is defined as LBUS dropping
below VIL(LBUS) for longer than the Bus
Activity Debounce time (tBDB).
1.3.2
READY MODE
The MCP2003/4 will go into Power Down mode on
falling edge of CS, or return to Operation mode if all
faults are resolved and the FAULT/TXE pin on the
MCP2004 is high.
Upon entering the Ready mode, VREN is enabled and
the receiver detect circuit is powered up. The transmit-
ter remains disabled and the device is ready to receive
data but not to transmit.
Upon VBB supply pin power-on, the device will remain
in Ready mode as long as CS is low. If CS transitions
high, the device will enter Operation mode. However, if

1.5.1
RECEIVE DATA OUTPUT (RXD)
1.5.3
WAKE UP INPUT (WAKE)
The Receive Data Output pin is a open drain (OD)
output and follows the state of the LIN pin.
This pin is only available on the MCP2003.
The WAKE pin has an internal 800K pull up to VBB. A
falling edge on the WAKE pin causes the device to
wake from Power Down mode. Upon waking, the
MCP2003 will enter Ready mode
1.5.2
CS (CHIP SELECT)
Chip Select Input pin. An internal pull-down resistor will
keep the CS pin low. This is done to ensure that no
disruptive data will be present on the bus while the
microcontroller is executing a Power-on Reset and an
I/O initialization sequence. The pin must detect a high
level to activate the transmitter.
1.5.4
FAULT/TXE
This pin is only available on the MCP2004. This pin is
bidirectional and allows disabling of the transmitter, as
well as fault reporting related to disabling the
transmitter. This pin is an open-drain output with states
as defined in Table 1-2. The transmitter is disabled
whenever this pin is low (‘0’), either from an internal
Fault condition or by an external drive. While the
transmitter is disabled, the internal 30 k pull-up
resistor on the LBUS pin is also disconnected to reduce
current.
If CS = 0 when the VBB supply is turned on, the device
stays in Ready mode. In Ready mode, the receiver is
on and the LIN transmitter driver is off.
If CS = 1 when the VBB supply is turned on, the device
will proceed to the Operation mode as soon as internal
voltages stabilize.
This pin may also be used as a local wake-up input
(Refer to Example 1-1). In this implementation, the
microcontroller I/O controlling the CS should be
converted to a high-impedance input allowing the
internal pull-down resistor will keep CS low. An external
switch, or other source, can then wake-up both the
transceiver and the microcontroller (if powered).
Note:
The FAULT/TXE pin is true (‘0’) whenever
the internal circuits have detected a short
or thermal excursion and have disabled
the LBUS output driver.
Note:
It is not recommended to tie CS high as
this can result the MCP2003/4 entering
Operation mode before the microcon-
troller is initialized and may result in
unintentional LIN traffic.

Note 1: The FAULT/TXE is valid after approximately 25 µs after TXD falling edge. This is to eliminate false fault
reporting during bus propagation delays.
1.5.5
TRANSMIT DATA INPUT (TXD)
1.5.7.1
Bus Dominant Timer
The Transmit Data Input pin has an internal pull-up.
The LIN pin is low (dominant) when TXD is low, and high
(recessive) when TXD is high.
The Bus Dominant Timer is an internal timer that deac-
tivates the LBUS transmitter after approximately
25 milliseconds of dominant state on the LBUS pin. The
timer is reset on any recessive LBUS state.
For extra bus security, TXD is internally forced to ‘1’
whenever the transmitter is disabled regardless of
external TXD voltage.
The LIN bus transmitter will be re-enabled after a
recessive state on the LBUS pin as long as CS is high.
Disabling can be caused by the LIN bus being exter-
nally held dominant, or by TXD being driven low. Addi-
tionally, on the MCP2004, the FAULT pin will be driven
low to indicate the Transmitter Off state.
1.5.5.1
TXD Dominant Timeout
If TXD is driven low longer than approximately 10 ms,
the LBUS pin is switched to Recessive mode and the
part enters TOFF mode. This is to prevent the LIN node
from permanently driving the LIN Bus dominant. The
transmitter is re-enabled on the TXD rising edge.

VOLTAGE REGULATOR ENABLE

Open source output is pulled high to VBB in all modes,
except Power Down.
1.5.7
LIN BUS (LBUS)
The bidirectional LIN Bus pin (LBUS) is controlled by the
TXD input. LBUS has a current limited open collector
output. To reduce EMI, the edges during the signal
changes are slope controlled and include corner
rounding control for both falling and rising edges.
1.5.10
EXPOSED THERMAL PAD (EP)
Do not electrically connect, or connect to Vss.
The internal LIN receiver observes the activities on the
LIN bus, and matches the output signal RXD to follow
the state of the LBUS pin.

Note 1: The maximum power dissipation is a function of TJMAX, JA and ambient temperature T . The maximum
A
allowable power dissipation at an ambient temperature is PD = (TJMAX - TA)JA. If this dissipation is
exceeded, the die temperature will rise above 150C and the MCP2003/4 will go into thermal shutdown.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
