Overview
Part: TJA1050
Type: High speed CAN transceiver
Description: High speed CAN transceiver with very low electromagnetic emission, improved unpowered node behavior, and bus pins protected against automotive transients, supporting baud rates from 60 kbaud up to 1 Mbaud.
Operating Conditions:
- Supply voltage: 4.75–5.25 V

- Baud rate: 60 kbaud up to 1 Mbaud
Absolute Maximum Ratings:
- Max supply voltage: +6 V
- Max junction/storage temperature: +150 °C
Key Specs:
- Supply current (dominant): 75 mA (max, V TXD = 0 V)
- Supply current (recessive): 10 mA (max, V TXD = V CC)
- Differential bus input voltage (dominant): 1.5–3 V (V TXD = 0 V)
- Propagation delay TXD to RXD: 250 ns (max, V S = 0 V)
- Differential receiver threshold voltage: 0.5–0.9 V
- TXD dominant time-out: 250–750 μs (V TXD = 0 V)
- Short-circuit output current (CANH): -95 mA (max, V CANH = 0 V, V TXD = 0 V)
- Short-circuit output current (CANL): 100 mA (max, V CANL = 36 V, V TXD = 0 V)
Features:
- Fully compatible with the 'ISO 11898' standard
- High speed (up to 1 Mbaud)
- Very low ElectroMagnetic Emission (EME)
- Differential receiver with wide common-mode range for high ElectroMagnetic Immunity (EMI)
- An unpowered node does not disturb the bus lines
- Transmit Data (TXD) dominant time-out function
- Silent mode in which the transmitter is disabled
- Bus pins protected against transients in an automotive environment
- Input levels compatible with 3.3 V and 5 V devices
- Thermally protected
- Short-circuit proof to battery and to ground
- At least 110 nodes can be connected.
Applications:
- High-speed automotive applications
- Nodes in a power-down situation in partially powered networks
