Product details

Overview

TJA1055T/CM,118 from NXP Semiconductors is a fault-tolerant low-speed CAN transceiver designed for automotive body electronics and chassis networks. It provides differential transmit/receive capability up to 125 kBd, supports up to 32 nodes on unshielded bus wires, and features automatic single-wire fallback during CANH or CANL faults - enabling continued communication in passenger car wiring systems with ground offset up to 1.5 V.

For engineers reviewing the TJA1055T/CM,118 datasheet, TJA1055T/CM,118 pinout, TJA1055T/CM,118 application, or TJA1055T/CM,118 equivalent, key selection criteria include its ±6 kV IEC 61000-4-2 ESD rating on CANH/CANL, 25–40 µA sleep-mode battery current (VBAT = 14 V), wake-up signaling on RXD/ERR without VCC, and pin-to-pin compatibility with TJA1054/TJA1054A for legacy system upgrades.

Technical Context

The TJA1055T/CM,118 implements dual-mode bus interface logic: differential operation under normal conditions (CANH/CANL thresholds at −3.2 V typical) and automatic failover to single-wire mode upon detection of short-to-battery (CANH), short-to-ground (CANL), or open-wire faults - using dedicated RTH/RTL termination control pins and internal comparators with time-out filtering to prevent RF false triggers.

Its low-power architecture supports three distinct states - sleep (INH high-Z, 25 µA IBAT), standby (INH HIGH), and power-on standby (ERR indicates VBAT flag) - all entered via STB/EN digital inputs, with wake-up enabled via bus edges or local WAKE pin (edge-triggered, 2.5–3.9 V threshold), while maintaining ERR/RXD wake signaling even when VCC is absent.

Key Specifications

Parameter	Value and Actual Design Meaning
Baud rate	Up to 125 kBd - supports low-speed CAN networks in automotive body control modules.
ESD protection	±6 kV IEC 61000-4-2 on CANH/CANL - ensures robustness against electrostatic discharge in assembly and service environments.
Sleep-mode IBAT	25–40 µA at VBAT = 14 V, −40 °C to +125 °C - enables ultra-low quiescent current for always-on vehicle networks.
Bus fault tolerance	Supports single-wire operation with ground offset ≤1.5 V - maintains communication during CANH short-to-VCC or CANL short-to-ground.
Dominant timeout	Integrated TXD dominant time-out - prevents permanent bus dominance due to MCU lockup or firmware failure.
Thermal shutdown	Triggers at 160–190 °C junction temperature - protects transmitter stages during overload or ambient overheating.
Supply voltage range	VCC = 4.75–5.25 V; VBAT = −0.3–+58 V - accommodates automotive load-dump transients and cold-crank conditions.

Pinout & Package

Package: SO14 (plastic small outline, 14 leads, 3.9 mm body width, SOT108-1).

Pin/Terminal	Circuit Role	Design Meaning
1 INH	Inhibit output	Drives external voltage regulator; floats in sleep mode to disable supply, pulled HIGH on wake-up.
2 TXD	Transmit data input	CMOS-level input controlling driver activation; includes dominant time-out safety function.
3 RXD	Receive data output	Open-drain output (TJA1055T/CM variant); signals received bus state and wake-up events even without VCC.
4 ERR	Error/wake-up indicator	Active-LOW output indicating bus fault, wake-up event, or VBAT power-on flag depending on mode.
5 STB	Standby control input	Digital input (with EN) selecting sleep/standby/power-on standby/normal operating modes.
6 EN	Enable control input	Digital input (with STB) determining operational state; failsafe logic holds LOW if VCC < 3.1 V.
7 WAKE	Local wake-up input	Edge-triggered (rising/falling); weak pull-up to VBAT prevents false triggers during open-wire conditions.
8 RTH	CANH termination bias	Connects to external resistor; switches to 75 µA pull-down during CANH short-to-battery detection.
9 RTL	CANL termination bias	Connects to external resistor; switches to 75 µA pull-up during CANL short-to-battery detection.
10 VCC	Logic supply	5 V nominal supply for internal logic; powers RXD/ERR drivers and control circuitry.
11 CANH	High-side CAN bus line	Differential bus terminal with ±58 V absolute max rating; includes integrated EMI filters and slope control.
12 CANL	Low-side CAN bus line	Differential bus terminal with ±58 V absolute max rating; matched to CANH for low EME emission.
13 GND	Ground reference	Primary signal and power return path; referenced for all voltage measurements and ESD protection.
14 BAT	Battery supply input	Direct connection to vehicle battery; powers internal regulators and enables wake-up signaling without VCC.

Key Features

Feature	Design Value
Fault-tolerant single-wire mode	Automatic switch to CANH-only or CANL-only transmission upon bus wire failure, preserving network availability.
Wake-up without VCC	RXD and ERR outputs remain functional during sleep/standby using only VBAT, enabling microcontroller wake-up before logic supply is active.
Integrated slope control	Controls CANH/CANL edge rates to meet automotive EMC requirements with unshielded twisted-pair cabling.
Dual-threshold receivers	Differential (−3.2 V) and single-ended (1.7 V on CANH, 3.3 V on CANL) thresholds ensure noise margin across all fault modes.
Fail-safe enable logic	STB/EN inputs internally forced LOW if VCC drops below 3.1 V, preventing undefined transceiver behavior during brownout.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fault-tolerant CAN transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TJA1054T/CM,118	Lacks wake-up signaling without VCC; lower ESD rating (±4 kV IEC 61000-4-2); no RTH/RTL bias control for single-wire termination.	Not suitable for systems requiring VBAT-only wake-up or enhanced fault-mode termination.	Select only for cost-sensitive legacy designs where TJA1055T/CM,118 features are unused.
SN65HVD251DR	Standard (non-fault-tolerant) CAN transceiver; no single-wire mode; 3.3 V/5 V compatible; higher ESD (±16 kV HBM) but no automotive-grade VBAT support.	Requires external protection for 12 V/24 V battery environments; unsuitable for degraded-bus operation.	Use only in non-automotive industrial CAN networks with stable 5 V supply and no wiring fault requirements.

Compared with TJA1054T/CM,118 and SN65HVD251DR, the TJA1055T/CM,118 uniquely delivers VBAT-powered wake-up, programmable single-wire termination via RTH/RTL, and automotive-grade fault tolerance - making it the sole choice for ISO 11898-3-compliant body electronics where bus degradation resilience is mandatory.

FAQ

What is the maximum bus speed supported by the TJA1055T/CM,118?

The TJA1055T/CM,118 supports a maximum baud rate of 125 kBd, optimized for low-speed Controller Area Network (CAN) applications in passenger car body electronics. This speed aligns with ISO 11898-3 specifications and ensures reliable operation over unshielded twisted-pair cabling with built-in slope control to limit electromagnetic emissions.

Does the TJA1055T/CM,118 support wake-up functionality when VCC is not powered?

Yes, the TJA1055T/CM,118 supports full wake-up signaling on pins RXD and ERR using only VBAT supply - even when VCC is absent. This allows the connected microcontroller to detect bus activity or local WAKE pin edges and initiate power-up sequencing before restoring logic supply, a key requirement for automotive always-on networks.

How does the TJA1055T/CM,118 handle CAN bus wiring faults?

The TJA1055T/CM,118 automatically detects seven defined bus failures (e.g., CANH short-to-battery, CANL open) and switches to single-wire transmission mode using either CANH or CANL. Termination is dynamically adjusted via RTH/RTL pins, and reception continues with mode-specific thresholds - all without interrupting communication or requiring MCU intervention.

What is the sleep-mode current consumption of the TJA1055T/CM,118?

In sleep mode, the TJA1055T/CM,118 draws 25–40 µA from the battery supply (IBAT) at VBAT = 14 V and ambient temperatures from −40 °C to +125 °C. This ultra-low quiescent current enables compliance with automotive static current budgets for modules that must remain responsive during vehicle off-states.

Is the TJA1055T/CM,118 pin-compatible with earlier NXP transceivers?

Yes, the TJA1055T/CM,118 is pin-to-pin compatible with the TJA1054 and TJA1054A, allowing direct replacement in existing designs. However, it adds enhancements including improved ESD performance (±6 kV IEC 61000-4-2), lower sleep current, and wake-up capability without VCC - requiring no PCB changes but enabling immediate system-level reliability improvements.
