Other Parts Discussed in Thread: TCAN1051
Hi Experts,
Could you please help to explain the design consideration of below two specs of the CAN transceiver?
- Common mode voltage: for old product such as TCAN1042, TCAN1051, the common mode voltage is +/-30V, but for TCAN1044, TCAN1057, the common mode voltage changed to +/-12V, could you please help to explain the reason why you made this change? Is it because the previous +/-30V is a little over spec? Where should customer choose +/-30V and where should choose +/-12V?
- Bus fault voltage: For device without “H”, the bus fault voltage is usually +/-58V, what’s your design consideration for it? Is it an industrial standard? Is it for 12V and 24V battery systems? For device with “H”, the bus fault voltage is +/-70V, why you choose 70V? Is it for 48V battery system? Thank you.
