Hi..
One of my customer is using TCAN1463DRQ1 CAN transceiver IC with STM32H5 nucleo board for evaluating TCAN1463DRQ1 CAN transceiver IC.
There are 4 operating modes for TCAN1463DRQ1 as mentioned in data sheet.
– Normal mode
– Silent mode
– Standby mode
– Low-power sleep mode
They are using PEAK CAN USB adaptor and PCAN view for monitoring CAN frames with proper CAN termination.
Please find below other pin configuration for your reference.
PIN3 - VCC - connected to +5V.
PIN5 - VIO - connected to +3.3V.
PIN7 - INH - Keep floating. Not connected.
PIN9 - WAKE - connected to +10V.
PIN10 - Vsup - connected to +10V.
PIN11 - INH_MASK - connected to ground through capacitor.
They are able to establish and verify CAN communication in Normal mode, but they are facing following issues when they tried to test the silent mode.
- They set the TCAN1463DRQ1 mode as a silent mode by setting standby and enable pin (please refer below image for your reference), but STM32H5 evaluation board doesn’t receive any CAN frame which they are sending from PCAN view.
And PCAN view shows bus heavy message status as soon as they send CAN message from PCAN view to STM32H5 eval board. They expect that in this condition nFault pin should go to logic low, but it still remains in logic high state.
Please let me know any additional information is required.
Thanks
Mitesh
