S32M244LC high-voltage detect threshold

YAN3 — Tue, 03 Sep 2024 02:47:47 GMT

I have a question about high voltage threshold Settings，S32M244LC‘s GDU will be closed when VSUP over 22.6V，Where can I set this value(such as set to 28V)，No description of this section is found in the RM &datasheet.

thanks

Hi Yan,

there is a possibility to set bit HDHVDCFG to 1 , in GDU/CFG register (S32M24x RM rev2, page 1165). With this bit set, thresholds VHVHDHA and VHVHDHD will be used for overvoltage detector. Thresholds VHVHDHA (min-typ-max: 30.65-32.5-34.6V) and VHVHDHD (min-typ-max: 29.65-31.5-33.6V) are defined in S32M2xx DS rev3, page 38/39

Best regards,

Pavel
