TJA1055

Enhanced fault-tolerant CAN transceiver

 

8. Limiting 

values

 

Mode 10 stands for: Pin STB = HIGH and pin EN = LOW.

(1) Mode change via input pins STB and EN.

(2) Mode change via input pins STB and EN; it should be noted that in the sleep mode pin INH is 

inactive and possibly there is no V

CC

. Mode control is only possible if V

CC

 of the transceiver is 

active.

(3) Pin INH is activated and pins RXD and ERR are pulled LOW after wake-up via bus or input 

pin WAKE.

(4) Transitions to normal mode clear the internal wake-up: wake-up interrupt flag and power-on flag 

are cleared.

(5) Transitions to sleep mode: pin INH is deactivated.
