FUNCTIONAL DESCRIPTION
The primary function of a CAN transceiver is to provide the
CAN physical layer as described in the ISO 11898
standard. In the TJA1041A this primary function is
complemented with a number of operating modes,
fail-safe features and diagnosis features, which offer
enhanced system reliability and advanced power
management functionality.
Operating modes
The TJA1041A can be operated in five modes, each with
specific features. Control pins STB and EN select the
operating mode. Changing between modes also gives
access to a number of diagnostics flags, available via
pin ERR. The following sections describe the five
operating modes. Table 1 shows the conditions for
selecting these modes. Figure 3 illustrates the mode
transitions when VCC, VI/O and VBAT are present.

Notes
1. Equivalent to discharging a 100 pF capacitor via a 1.5 kseries resistor (6 kV level with pin GND connected to
ground).
2. Equivalent to discharging a 200 pF capacitor via a 0.75 µH series inductor and a 10 series resistor.
3. Junction temperature in accordance with IEC 60747-1. An alternative definition is: Tvj = Tamb + P × Rth(vj-amb), where
Rth(vj-amb) is a fixed value. The rating for Tvj limits the allowable combinations of power dissipation (P) and ambient
temperature (Tamb).
