产品描述

SIT1145AQT/FD adds selective wake-up to a CAN FD physical interface. The controller can configure which standard CAN wake-up frames should activate the node, allowing other traffic to pass while that node remains in standby or sleep. Its INH output can also control the external regulator supplying the rest of the node.

The /FD suffix denotes FD-passive filtering during selective wake-up. While waiting for a valid wake-up frame, the device can ignore CAN FD frames so that a sleeping node using an ordinary CAN controller does not generate bus errors in a mixed CAN and CAN FD network.

SPI provides configuration and status access. The documented minimum clock period is 250 ns in normal or standby mode and 1 us in sleep, so host software must account for the slower sleep-state access timing. This SOP-14 order uses the base SIT1145AQ supply limits, including a 5.5 to 40 V battery input and a 2.85 to 5.5 V I/O rail.
