ZHCSPG0 December 2021 TCAN1167-Q1
PRODUCTION DATA
The RXD output pin is asserted low while in standby mode if the a wake event or a fault is detected. Note that a POR counts as a wake event and will also cause RXD to latch low.
In standby mode a fail-safe timer, tINACTIVE, is enabled. The tINACTIVE timer add an additional layer of protection by requiring the system controller to configure the TCAN1167-Q1 to normal mode before it expires. This feature forces the TCAN1167-Q1 to transition to its lowest power mode, sleep mode, if the processor does not come up properly.
