TJF1051
High-speed CAN transceiver
Rev. 01 — 10 August 2010
Product data sheet
1. General description
The TJF1051 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 industrial applications,
providing differential transmit and receive capability to (a microcontroller with) a CAN
protocol controller.
The TJF1051 is a step up from the TJA1050 high-speed CAN transceiver. It offers
improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD)
performance, and also features ideal passive behavior to the CAN bus when the supply
voltage is off.
The TJF1051 can be interfaced directly to microcontrollers with supply voltages from
3 V to 5 V
These features make the TJF1051 an excellent choice for all types of HS-CAN networks,
in nodes that do not require a standby mode with wake-up capability via the bus.
2. Features and benefits
2.1 General
Fully ISO 11898-2 compliant
Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
VIO input allows for direct interfacing with 3 V to 5 V microcontrollers
2.2 Low-power management
Functional behavior predictable under all supply conditions
Transceiver disengages from the bus when not powered up (zero load)
2.3 Protection
High ESD handling capability on the bus pins
Transmit Data (TXD) dominant time-out function
Undervoltage detection on pins VCC and VIO
Thermally protected
