7.4 Device Functional Modes

The TCAN1162-Q1 has five modes: normal, standby, sleep, fail-safe, and off mode. Operating mode selection is made via the nSLP input terminal in conjunction with supply conditions, temperature conditions, and wake events.

Table 7-2 Mode Overview
Block Normal Standby Sleep Fail-Safe
VFLT On On/Off(1)(2) Off Off
INH On Active Off Off
Low Power CAN RX Off Active Active Active
RXD VIO VIO High impedance(3) VIO
(1) VFLT is switched on in standby mode if nSLP is pulled high enabling normal mode.
(2) VFLT is switched on in standby mode if a valid WUP is detected on the CAN bus. If the nSTB pin is not pulled high within the timeout for bus inactivity window timer (t(silence)) VFLT is switched off again.
(3) VIO if VIO is present.
