Hello I use the S32K148 micro controller supplied with 3.3V which comunique with a Can tranceiver supplied with 5V
the voltage at the terminal of A1 and A2 is 2.8V
B1 and B2 output a voltage which oscillates between 2.8V and 5V.
is it normal to behave like this?
I share with you my schematic as an attachment
thank you for your support
0.1uF should be OK,pull up resistors should be 2.2K.
0.1uF should be no problem.
Pull up resistor should be added in A/B side,such as 2.2K.
Do you have decouple capacitors of VCCA/B side?
do you have pull up on A/B side?
Hi Sir
Thank for your answer.
I have 100nf 16V capacitor for VCCA and VCCB
i dont have a pull up in A/B
shoud place a capacitor and if the valu of capacitor is OK?
what is the valu of A/B pull up resistor ?
thank you
