TJA1051

Part: TJA1051 — NXP Semiconductors

Type: High-speed CAN Transceiver

Description: A high-speed CAN transceiver that provides an interface between a Controller Area Network (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.

Operating Conditions:

• Supply voltage (VCC): 4.5 V to 5.5 V
• I/O supply voltage (VIO): 2.8 V to 5.5 V (for TJA1051T/3 and TJA1051TK/3)
• Operating temperature (Tvj): -40 °C to +150 °C
• Data rates: up to 5 Mbit/s in the CAN FD fast phase

Absolute Maximum Ratings:

• Max voltage on CANH, CANL: -58 V to +58 V
• Max voltage on any other pin: -0.3 V to +7 V
• Max differential voltage (CANH-CANL): -27 V to +27 V
• Max virtual junction temperature (Tvj): +150 °C
• Max storage temperature (Tstg): -55 °C to +150 °C

Key Specs:

• Supply current (ICC) Normal mode, recessive: 5 mA (typ)
• Supply current (ICC) Normal mode, dominant: 50 mA (typ)
• Supply current (ICC) Silent mode: 1 mA (typ)
• Differential output voltage (VO(dif)) dominant: 1.5 V to 3 V (RL = 45 Ω to 65 Ω)
• Differential receiver threshold voltage (Vth(RX)dif): 0.5 V to 0.9 V
• Differential receiver hysteresis voltage (Vhys(RX)dif): 50 mV to 200 mV
• Undervoltage detection voltage (Vuvd(VCC)): 3.5 V to 4.5 V
• ESD voltage (CANH, CANL): ±8 kV (IEC 61000-4-2)

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
• 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 the microcontroller to switch the transceiver to a very low-current Off mode (TJA1051T/E)
• High ElectroStatic Discharge (ESD) handling capability on the bus pins
• Transmit Data (TXD) dominant time-out function
• Undervoltage detection on pins VCC and VIO
• Thermally protected

Applications:

• High-speed CAN applications in the automotive industry
• Suitable for 12 V and 24 V systems
• All types of HS-CAN networks (in nodes that do not require 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 x 3 x 0.85 mm)
