HSD_OT
High-side MOSFET over-temperature fault. Prevents start-up switching while
fault is activated and then monitored again after hand over to secondary
control mode.

4000h
A
AMB_OT
Low-side controller ambient over temperature fault. Prevents start-up
switching while fault is activated and then monitored again after hand over
to secondary control mode.
13

I
BPH_UVN
High-side BPH undervoltage. Prevents start-up switching while fault is
activated. Not monitored in secondary control.

1000h
I
L_OV
Line overvoltage – activation of this fault L = OV+ causes device to stop
switching and triggers latching/non-latching response based on PP pin
selection. Restart occurs when both auto-restart period is completed and
fault clears L = OV-. Fault monitored in all switching modes.
11

A
L_UV
Line undervoltage. Prevents start-up switching while fault is activated. Fault
monitored in all switching modes.

A/L
EXT_FAULT
External Fault on PP pin. Can be latching/non-latching based on PP pin
selection and/or device SKU. External circuit required to trigger this fault.
Often used for secondary V
OUT OV detection.

REM_OFF
Remote-off on PP pin (note: when L pin not used REM_OFF also generated
concurrently at EXT_FAULT ). Prevents start-up switching while fault is
activated.

LOST_FL_FAULT
Lost FluxLink is monitored after start-up and hand over to secondary control
mode and only when not in burst-mode. This occurs after XXXus of
observing an unchanged/static FL signal while no in burst-mode. This fault
can often be triggered when secondary bias is lost (BPS_UV), and secondary
device stops operating.
