CAN FD transceiver

ISO 11898-2:2016 compliant.

SAE J2284 compliant.

The voltages are referred to GND and currents are assumed positive when the current flows into the pin.

6 V < VSREG < 18 V, 4.8 V < Vcansup. < 5.2 V, TJ = -40°C to 150°C, unless otherwise specified.

-12 V ≤ (CANH + CANL)/2 ≤ 12 V.

ITRCV

Transceiver current

consumption during

normal mode

Active mode:

RL = from 50 Ω to 65 Ω, CRXD = 15 pF,

70% VRXDC (rising) - 30% VRXDC (falling),

TXD rise and fall time = 10 ns

(10% - 90%, 90% - 10%),

Test signal to be applied on the TXD input of

the implementation is a square wave signal with

a positive duty cycle of 1/6 and a period of six

times the nominal recessive bit width

rectangular pulse signal

TTXDC = 6*TBIT(2),

high pulse 1*TBIT, low pulse 5*TBIT

1. At VSREG < VSREG_Tranmitter(min) the transceiver shall enter high impedance state.

2. The bit time TBIT is the nominal bit time at a given bit rate (TBIT = 1/BR). For example: at BR = 2 Mb/s => TBIT = 500 ns.
