ZHCSPG0 December 2021 TCAN1167-Q1
PRODUCTION DATA
Reset mode is a low power mode of the TCAN1167-Q1 where the nRST pin is asserted low allowing the controller to power up correctly. In this state the CAN transmitter and receiver are off, the bus pins are biased to ground, and the transceiver cannot send or receive data.
While in reset mode the low power receiver actively monitors the CAN bus for a valid wake-up pattern. If a valid wake-up pattern is received the CAN bus pins transition to the CAN autonomous active state where CANH and CANL are internally biased to 2.5 V from the VSUP power rail. The reception of a valid wake-up pattern generates a wake-up request by the CAN transceiver that is output to the RXD pin.
The TCAN1167-Q1 will enter reset mode due to following conditions:
The TCAN1167-Q1 will enter reset mode upon clearing any of the following fault conditions and leaving fail-safe mode:
