TJA1053 Description
The TJA1053 is the interface between the CAN protocol controller and the physical bus. It is primarily intended for low-speed applications, up to 125 kbaud, in passenger cars. The device provides differential transmit capability but will switch in error conditions to a single-wire transmitter and/or receiver.
TJA1053 Key Features
- Baud rate up to 125 kbaud
- Up to 32 nodes can be connected
- Supports unshielded bus wires
- Low RFI due to built-in slope control function
- Fully integrated receiver filters
- Permanent dominant monitoring of TXD. Bus failure management
- Supports one-wire transmission modes with ground offset voltages up to 1.5 V
- Automatic switching to single-wire mode in the event of bus failure
- Automatic reset to differential mode if bus failure is removed. Protection
- Short-circuit proof to battery and ground in 12 V powered systems
