SLVSGT3 December 2022 DRV8317
PRODUCTION DATA
DRV8317 provides user configurable thresholds (VVMUV_WARN_FALL, VVMUV_WARN_RISE) for VM under voltage warn protection. If at any time, voltage on VM pin falls below the VVMUV_WARN_FALL threshold, action is taken as per VMUV_WARN_MODE configuration. There are four settings for VMUV_WARN_MODE: automatic retry with slow and fast retry time, report only and disabled. The threshold for the VM under voltage warn fault condition to be removed is set by VVMUV_WARN_RISE. This fault can be enabled/ disabled using VMUV_WARN_EN. In DRV8317H, this fault is enabled by default and set to report only mode (VMUV_WARN_MODE set to 10b).
