8.4.3 Standby Mode

This is the low-power mode of the TCAN1476-Q1. The CAN driver and main receiver are switched off and bi-directional CAN communication is not possible. The low-power receiver and bus monitor circuits are enabled to allow for RXD wake-up requests via the CAN bus. A wake-up request is output to RXD1 or RXD2 depending on the channel which receives the WUP as shown in Figure 8-8. The local CAN protocol controller should monitor RXD1 and RXD2 for transitions (high-to-low) and reactivate the device to normal mode by pulling the STB1 and STB2 pins low. The CAN bus pins are weakly pulled to GND in this mode (see Figure 8-5 and Figure 8-6).

When the TCAN1476V-Q1 is in standby mode, only the VIO supply is required; therefore, the VCC may be switched off for additional system level current savings.
