Hi sir,
Refer to TCAN1042 application design, TCAN1042VDRBRQ1 VIO is connected to 3.3V and that is same power rail with microcontoller.
Since we need to power off transceiver and make the CAN BUS be high impedance, also select the cost effective design.
Can I use microcontroller's GPIO (driving level can be 3.5mA.min) to control TCAN1042's VIO? I checked the current rating, it is sufficient, but I'm worry about the side effect.
Please advice if this design is proper or not. Thanks.
Hedy
