SLVSFY9B June 2021 – August 2021 DRV8212
PRODUCTION DATA
The DRV8212 enters a fault mode when a fault is encountered. This protects the device and the output load. The device behavior in the fault mode is described in Section 8.3.3 and depends on the fault condition. The device leaves the fault mode and re-enters the active mode once the recovery condition is met. Table 8-8 summarizes the fault conditions, response, and recovery.
