MCP2003/4/3A/4A
1.0 DEVICE OVERVIEW
The MCP2003/4/3A/4A devices provide a physical
interface between a microcontroller and a LIN bus.
These de vices wi ll translate th e CMOS/TTL logic level s
to LIN logic level, and vice versa. It is intended for
automotive and industrial applications with serial bus
speeds up to 20 Kbaud.
LIN spec if ica tio n 2.1 requires that the transceiver of all
nodes in the syste m is conn ected via the LIN pin, ref er-
enced to ground and with a maximum external
termination resistance load of 510Ω from LIN bus to
battery supply. The 510Ω corres pon ds to 1 master an d
15 slave node s.
The VREN pin can be used to driv e t he l ogi c i npu t of an
external voltage regulator. This pin is high in all modes
except for Power-Down mode.
1.1 External Protection
1.1.1 REVERSE BATTERY PR OTECTION
An external reverse-battery-blocking diode should be
used to provide polarity protection (see Example 1-1).
1.1.2 TRANSIENT VOLTAGE
PROTECTION (LOAD DUMP)
An external 43V transient suppressor (TVS) diode,
between VBB and ground, with a 50Ω transient
protection resistor (RTP) in series with the battery
supply and the VBB pi n serve to p rotect the d evice from
power transients (see Example 1-1) and ESD events.
While this protection is optional, it is considered good
engineering practice.
1.2 Internal Protection
1.2.1 ESD PROTECTION
For component-level ESD ratings, please refer to the
maximum operation specifications.
1.2.2 GROUND LOSS PROTECTION
The LI N Bu s spe cifi cat ion s tates that th e LIN pin mu st
transition to the recessive state when ground is
disconnected. Therefore, a loss of ground effectively
forces the LIN line to a high-impedance level.
1.2.3 THERMAL PROTECTION
The thermal protection circuit monitors the die
temperature and is able to shut down the LIN
transmitter.
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 bus out put overload
Increase in die temperature due to increase in
environment temperature
Driving the TXD and checking the RXD pin makes it
possib le to determine whether there is a bus co ntention
(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
temperat ure has fallen below the recov ery temperature
threshold. See Figure 1-1.

1.3 Modes of Operation
For an overview of all operational modes, refer to
Table 1-1.
1.3.1 POWER-DOWN MODE
In Power-Down mode, everything is off except the
wake-up section. This is the lowest power mode. The
receiver is off, thus its output is open-drain.
On CS go ing to a h igh lev el or a fal li ng ed ge on WAKE
(MCP2003/MCP2003A only), the device will enter
Ready Mode as soon as internal voltage stabilizes.
Refer to the AC Spec tabl e. In additi on, LIN bu s activity
will c hange the de vice from po wer-dow n mode to read y
mode; MCP2003/4 wakes up on a falling edge of LIN
bus and M CP20 03/4A on a risi ng edge , followi ng a low
level lasting at least 20 µS of time. Refer to Figure 1-2
Figure 1-5 about remote wake up. If CS is held high
as the device transitions from Power-Down to Ready
mode, the device will transition to either Operation or
Transmitter Off mode, depending on TXD input, as
soon as internal voltages stabilize.
1.3.2 READY MODE
Upon entering the Ready mode, VREN is enabled and
the receiver detect circuit is powered up. The transmit-
ter rema ins disabled and th e device i s read y to rec eiv e
data but not to transmit.
Upon VBB supply pin power-on, the device will remain
in Ready mode as long as CS is low. When CS transi-
tions hi gh, the device wil l e ithe r en ter Operation mod e,
if TXD pin is held high, or the device will enter Trans-
mitter Off mode, if TXD pin is held low.
1.3.3 OPERATION MODE
In this mode, all internal modules are operational.
The device will go into the Power-Down mode on the
falling edge of CS. For the MCP2003/4 device, a
specific process should be followed to put all nodes into
Power-down mode. Refer to Section 1.6 “Enter
Power-Down Mode” and Figure 1-6. The device will
enter Transmitter Off mode in the event of a Fault
condition. These include: thermal overload, bus
contention and TXD timer expiration.
The MCP2004/2004A device can also enter
Transmitter Off mode if the FAULT/TXE pin is pulled
low. The VBB-LBUS pull-up resistor is connected only
in Operation mode.
1.3.4 TRANSMITTER OFF MODE
Transmitter Off mode is reached whenever the
transmi tter is disable d either du e to a Fault co ndition or
pulling the nFAULT/TXE pin low on the MCP2004/
2004A. The fault conditions include: thermal overload,
bus contention or TXD timer expiration.
The device will go into Power-Down mode on the falling
edge of CS, or r eturn to Opera tion m ode if all fa ult s ar e
resolved and the FAULT/TXE pin on the MCP2004/
2004A is high.

1.5 Pin Descriptions
TABLE 1-2: PINOUT DESCRIPTIONS
1.5.1 RECEIVE DATA OUTPUT (RXD)
The Receive Data Output pin is an open drain (OD)
output and follows the state of the LIN pin, except in
Power Down mode.
1.5.2 CS (C HIP SE LEC T )
This is the Chip Select Input pin. An internal pull-down
resisto r will ke ep the CS p in low. Thi s is done to ensure
that no disruptive data will be present on t he bus wh ile
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. An internal Low-
Pass filter, with a typical time constant of 10 µS,
prevents unwanted wake-up (or transition to Power
Down mode) on glitches.
If CS = 0 when the VBB supply is turned on, the device
goes to Ready mode as soon as internal voltages sta-
bilize , a nd st ays t here a s lon g as the C S pin i s hel d low
(0). In Ready mode, the receiver is on, and the LIN
transmitter driv er is off.
If CS = 1 when the VBB supply is turne d on, the dev ic e
will proceed to Operation mode, or TXOFF (refer to
Figure 1-2 – Figure 1-5), 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 to keep CS low. An external
switch, or other source, can then wake-up both the
transceiver and the microcontroller (if powered). Refer
to Section 1.3 “Modes of Operation”, for detailed
operation of CS.
1.5.3 WAKE UP INPUT (WAKE)
This pin is only available on the MCP2003/2003A.
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
MCP2003/3A will enter Ready mode.
1.5.4 FAULT/TXE
This pin is on ly ava ilabl e on the MCP2 004/20 04A. Thi s
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 1-3: “FAULT/
TXE Truth Table”. 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 kΩ pull-up
resi sto r on the LBUS p in is als o disconne cte d to reduce
current.
TABLE 1-3: FAULT/TXE TRUTH TABLE
1.5.5 TRANSMIT DATA INPUT (TXD)
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.
For extra bus security, TXD is internally forced to ‘1
whenever the transmitter is disabled regardless of
external TXD voltage.
1.5.5.1 TXD Dominant Timeout
If TXD is driven low for longer than approximately 25
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 reenabled on TXD risi ng edge.
1.5.6 GROUND (VSS)
This is the Ground pin.
1.5.7 LIN BUS (LBUS)
The bid irectional L IN Bus pin (LBUS) is controll ed 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.
The intern al LIN rec ei ver observ es the ac tiv iti es on th e
LIN bus, and matches the output signal RXD to follow
the state of the LBUS pin.
1.5.7.1 Bus Dominant Timer
The Bus Dominant Timer is an internal timer that
deactivates the LBUS transmitter after approximately
25 millisecond s of dom inant st ate on the LBUS pin. The
timer is reset on any recessive LBUS state.
The LIN bus transmitter will be reenabled after a
recessive state on the LBUS pin as long as CS is high.
Disabling can be caused by the LIN bus being
externally held dominant, or by TXD being driven low.
Additionally, on the MCP2004/2004A, the FAULT pin
will be driven low to indicate the Transmitter Off state.
1.5.8 BATTERY (VBB)
This is the Battery Positive Supply Voltage pin.
1.5.9 VOLTAGE REGULATOR ENABLE
OUTPUT (VREN)
This is the External Voltage Regulator Enable pin.
Open source output is pulled high to VBB in all modes,
except Power-Do w n.
1.5.10 EXPOSED THERMAL PAD (EP)
Do not electrically connect, or connect to Vss.
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.

MCP2003/4/3A/4A
1.6 MCP2003/4 and MCP2003A/4A
Difference Details
The differences between the MCP2003/4 and the
MCP2003/4A devices are isolated to the wake-up
functio nal ity . The cha nges were i mp lem en ted to make
the device more robust to LIN bus conditions, outside
of the normal operating conditions. The MCP2003/4
will wake-up from Power Down Mode during any LIN
falling edge held low longer than 20us.
In the case where a LIN system is designed to
minimize stand-by current by disconnecting all bus
pull-ups resistors (including the external master pull-
up resistor to VBB), the original MCP2003/4 could
wake up, if the floating bus drifted to a valid low level.
The MCP2003/4A revisions were modified to require a
rising edge after a valid low level. This will prevent an
undesired system wake-up in this scenari o, while
maintaining functional capability with the original
version.
It should be noted that the original MCP2003/4 meets
all LIN transceiver specification requirements and
modules can be designed to pass all LIN system
requirem ent s. H owev er, whe n all bus pu ll-u p res istors
are disconnected, the MCP2003/4 requires the
module designer to write firmware to monitor the LIN
Bus after any wake-up e vent to prevent th e transceiver
from automat ically transitioning fr om Ready mode to
Operational mode.
If the MCP2003 /4 is pla ce d into Operation al mo de,
VBB-LBUS pull-u p resistor is automatically connected,
which will raise the LIN bus to a recessive level; then
putting the device to Power-Down mode may cause
LBUS to be floating, and thus wake up all bus nodes.
To prevent this, the designer should insure TXD
(MCP2003) or TXE (MCP2004) is held low until valid
bus activity is verified (see Figure 1-6). This will
ensure th e transce iver transitio ns from Ready mode to
Transmi tter Off mode , until bu s activi ty can b e verified .
In the case of valid bus activity, the transceiver can
shift to Operation mode, while if there is no bus
activity, the device can be again placed into Power
Down. Th e design practices neede d to accomp lish this
are fully detailed in Tech Brief TB3067 - “MCP2003
Power-Down Mode a nd Wak e-Up Handling in Case
of LIN Bus Loss” (DS93067).
The revised MCP2003/4A devices now eliminate the
need for firmware to prevent system wide wake-up.
The revised devices now require a longer valid bus
low (see updated tBDB value in the Specification
tables and FIGURE 2-7: “MCP2003A/4A Remote
Wake-up”), which enable s a rising ed ge detect ci rcuit.
The device will now only wake up after a rising edge,
following a low longer than tBDB. While the module
designer can still hold TXD (MCP2003) or TXE
(MCP2004) low during wake-up, to enter Transmitter
Off mode from Ready mode, it is not required to
prevent an advertent system wake-up.
In addition to the longer tBDB value, the time from
wake-up detect to VREN enable is shortened as
documented in the Specification table.
