TJA1053 General 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. The TJA1053 is derived from the PCA82C252. 1. It is better equipped for networks with more than 15 nodes 2. A timer has been integrated at the TXD input to prevent a permanent dominant state 3. Reduced supply current in VCC standby mode 4. CANH output driver is disabled in the event that CANH is short-circuited to battery failure mode.

TJA1053 Features

Optimized for in-car low-speed communication
· 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
· Thermally protected
· Bus lines protected against transients in an automotive environment
· An unpowered node does not disturb the bus lines.
Support for low-power modes
· Low current sleep/standby mode with wake-up via the bus lines
· Power-on reset flag on the output.

TJA1053T General Description

The TJA1053T is designed as one kind of fault-tolerant CAN transceiver (interface between the protocol controller and the physical wires).It provides differential transmit capability but will switch in error conditions to single-wire transmitter and/or receiver.

Features of the TJA1053T are:(1)automatic reset to differential mode if bus failure is removed;(2)baud rate up to 125 kBaud;(3)up to 32 nodes can be connected;(4)supports unshielded bus wires;(5)permanent dominant monitoring of transmit data input;(6)supports single-wire transmission modes with ground offset voltages up to 1.5 V;(7)low current sleep and standby mode with wake-up via the bus lines;(8)power-on reset flag on the output;(9)an unpowered node does not disturb the bus lines;(10)short-circuit proof to battery and ground in 12 V powered systems.

The absolute maximum ratings of the TJA1053T can be summarized as:(1)supply voltage on pin VCC:-0.3 to +6 V;(2)battery voltage on pin BAT:-0.3 to +40 V;(3)DC voltage on pins 2 to 6:-0.3 to VCC+0.3 V;(4)DC voltage on pin CANH:-40 to +40 V;(5)DC voltage on pin CANL:-40 to +40 V;(6)transient voltage on pins CANH and CANL:-150 to +100 V;(7)electrostatic discharge voltage human body model:-2.0 to +2.0 kV;(8)electrostatic discharge voltage machine model:-200 to +200 V;(9)storage temperature:-55 to +150°C;(10)virtual junction temperature:-40 to +150°C.If you want to know more information such as the electrical characteristics about the TJA1053T,please download the datasheet in www.seekic.com or www.chinaicmart.com .
