12.4.3 Current Limit Protection
The DRV7308 integrates three comparators to protect the device, and external motor load, due to overload scenarios. DRV7308 has three integrated comparators, each monitoring voltage at SLA, SLB, and SLC pins separately. A voltage less than 2V at the ILIMIT pin enables the current limit circuitry and when the SLx voltage goes beyond the ILIMIT pin voltage, the device turns off all GaN FETs for a time tF_CLR. The GaNFETs turn on again after tF_CLR time elapses, depending on the status of input control signals. The current limit is reported by driving the nFAULT pin low.
