Figure 14. Cycle-By-Cycle Current Regulation

No device functionality is affected when the nFAULT pin is pulled low for the current chopping indicator. The

nFAULT pin is only used as an indicator and the device will continue normal operation. To distinguish from a

device fault (outlined in the Protection Circuits section) from the current chopping indicator, the nFAULT pin can

be compared with the control inputs. The current chopping indicator can only assert when the control inputs are

commanding a forward or reverse drive state (Figure 10). If the nFAULT pin is pulled low and the control inputs

are commanding the high-Z or slow-decay states, then a device fault has occurred.
