24V SBC ASIL B

[Nikhils]

Hi Sir

We are using FS2320X for 12V ASIL B Motor control application .

We got to know that its OV Threshold is upto 22v and cant be used for 24V system !

Is there any ASIL-B SBC that support 24V system ?

Hi Nikhil,

The FS23 can be used in 24 systems when a high-voltage buck is used in front of it. This is described in the AN14129, chapter "FS23 for a 24V application". 

Note that this AN14129 is classified as a secure file (requiring an NDA) and can be downloaded from the FS23 product website (under Documents - Secure files).

We currently develop the FS27 supporting the 24 systems without the need for a high-voltage buck regulator. However, its release is planned for Q3 2025 and it does not have an internal CAN transceiver.

BRs, Tomas
