ZHCSQV1C March 2020 – December 2022 TCAN1463-Q1
PRODUCTION DATA
Standby mode is a low-power mode where the driver and receiver are disabled, reducing current consumption. However, this is not the lowest power mode of the device since the INH terminal is on, allowing the rest of the system to resume normal operation.
During standby mode, a wake-up request (WAKERQ) is indicated by the RXD terminal being low. The wake-up source is identified via the nFAULT pin after the device is returned to normal mode.
In standby mode, a fail-safe timer called Sleep Wake Error (SWE) timer is enabled. The timer adds an additional layer of protection by requiring the system controller to configure the transceiver to normal mode before it expires. This feature forces the TCAN1463-Q1 to transition to its lowest power mode, sleep mode, after tINACTIVE if the processor does not come up properly and fails to transition the device to Normal mode.
