Part: TJA1051 — NXP Semiconductors

Type: High-speed CAN transceiver

Description: High-speed CAN transceiver providing an interface between a CAN protocol controller and the physical two-wire CAN bus, compliant with ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, supporting data rates up to 5 Mbit/s in CAN FD fast phase.

• Supply voltage (VIO): 2.8–5.5 V (for TJA1051T/3 and TJA1051TK/3)
• Virtual junction temperature: -40 to +150 °C
• Data rates: up to 5 Mbit/s

Absolute Maximum Ratings:

• Max voltage on CANH, CANL pins: +58 V
• Max voltage on any other pin: +7 V
• Max junction temperature: +150 °C
• Max storage temperature: +150 °C

Key Specs:

• Supply current (Normal mode, bus recessive): 2.5 mA (min), 5 mA (typ), 10 mA (max)
• Supply current (Normal mode, bus dominant): 20 mA (min), 50 mA (typ), 70 mA (max)
• Supply current (Silent mode): 0.1 mA (min), 1 mA (typ), 2.5 mA (max)
• Undervoltage detection voltage on VCC: 3.5 V (min), 4.5 V (max)
• Undervoltage detection voltage on VIO: 1.3 V (min), 2.0 V (typ), 2.7 V (max)
• Differential output voltage (dominant, RL = 45–65 Ω): 1.5 V (min), 3 V (max)
• Differential receiver threshold voltage: 0.5 V (min), 0.7 V (typ), 0.9 V (max)
• ESD voltage (CANH and CANL, IEC 61000-4-2): -8 kV (min), +8 kV (max)

Features:

• ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant
• Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase
• Suitable for 12 V and 24 V systems
• Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
• VIO input allows for direct interfacing with 3 V to 5 V microcontrollers (TJA1051T/3 and TJA1051TK/3)
• EN input allows switching to a very low-current Off mode (TJA1051T/E)
• Transmit Data (TXD) dominant time-out function
• Undervoltage detection on pins VCC and VIO
• Thermally protected

Applications:

• High-speed CAN networks in the automotive industry
• Nodes not requiring a standby mode with wake-up capability via the bus

Package:

• SO8 (plastic small outline package; 8 leads; body width 3.9 mm)
• HVSON8 (plastic thermal enhanced very thin small outline package; no leads; 8 terminals; body 3 × 3 × 0.85 mm)

TJA1051T/E Pinout

Notes

• Pin 5 function is variant-specific: TJA1051T/E uses EN (enable control input); other variants in the family use n.c. (not connected) or VIO (supply voltage for I/O level adapter).
• This pinout is extracted from the text table and applies specifically to the TJA1051T/E variant as indicated in the datasheet.
• No pin diagram image was provided; pin numbers are taken directly from the "Pin" column of the source table.

According to IEC 60747-1.
