Table 8-3 applies when the DIAG_EN pin is enabled.

Table 8-3 Fault Table

CONDITIONS	ENx⁽²⁾	OUTx⁽²⁾	THER⁽²⁾	CRITERION⁽²⁾	CS	FAULT	FAULT RECOVERY
Normal	L	L	—	—	0	H	—
Normal	H	H	—	—	In linear region	H	—
Overlaod, short to ground	H	L	—	Current limit triggered	V_{CS_FAULT}	L	Auto
Open load⁽¹⁾, short to power, reverse polarity	L	H	—	V_IN – V_OUTx < V_{OL_OFF}	V_{CS_FAULT}	L	Auto
Thermal shutdown	H	—	L	T_SD triggered	V_{CS_FAULT}	L	Output auto-retry. Fault recovers when T_J < T_(SD,rst) or when INx toggles.
Thermal shutdown	H	—	H	T_SD triggered	V_{CS_FAULT}	L	Output latch off. Fault recovers when INx toggles.
Thermal swing	H	—	—	T_SW triggered	V_{CS_FAULT}	L	Auto

(1) An external pullup is required for open-load detection.

(2) L = logical zero (false), H = logical one (true), — = don't care
