Tool/software:
Hello, team.
We use the TCAN1043A-Q1 CAN IC INH pin to enable the board's pre-regulated power supply. Our board has three pre-regulated supplies (12V0, 5V0, and 1V8), which are all needed for the TCAN IC power supplies.
The regulators that we will utilize to power the TCAN (VCC and VIO) require enable control via the INH pin.
The requirement is as follows: initially, we will have Vsup power going to TCAN; if everything is well, we expect TCAN to fall into standby mode, causing INH output to be high, which we will utilize to activate the other two regulators, power the rest of the peripherals on the board, and restore TCAN to normal operation. And when the TCAN is configured to sleep mode, it should disable the 5v0 and 1v8 regulators.
So the question is during power up of the TCAN, is it depending only on VSUP to be good or even VCC and VIO to get TCAN to standby state. If so, then is there any way I can control the sequence of the same regulators which supply power to TCAN IC.
