TJA1050U

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
• Operating temperature: -40 to +150 °C (virtual junction temperature)
• 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:
