TJA1051T中文资料数据手册PDF规格书

General description

The TJA1051 is a high-speed CAN transceiver that provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed (up to 1 Mbit/s) CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

Features and benefits

General

■ Fully ISO 11898-2 compliant

■ Suitable for 12 V and 24 V systems

■ Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)

■ VIO input on TJA1051T/3 and TJA1051TK/3 allows for direct interfacing with 3 V to 5 V microcontrollers (available in SO8 and very small HVSON8 packages respectively)

■ EN input on TJA1051T/E allows the microcontroller to switch the transceiver to a very low-current Off mode

Low-power management

■ Functional behavior predictable under all supply conditions

■ Transceiver disengages from the bus when not powered up (zero load)

Protection

■ High ElectroStatic Discharge (ESD) handling capability on the bus pins

■ Bus pins protected against transients in automotive environments

■ Transmit Data (TXD) dominant time-out function

■ Undervoltage detection on pins VCC and VIO

■ Thermally protected
