for the over-current fault blanking time, illustrated in
Bit OD2 reports when the over-current detection timeout
feature is active. OD3 reports whether the open load circuitry
is active.
Note The FS pin reports a fault and is reset by a new Switch-ON
command (via SPI or direct input IN).

OD7 (x) = Don’t care.
OD6 (OTF) = Over-temperature Flag.
OD5 (OCHF) = Over-current High Flag. (This fault is latched.)
OD4 (OCLF) = Over-current Low Flag. (This fault is latched.)
OD3 (OLF) = Open Load Flag.
OD2 (UVF) = Under-voltage Flag. (This fault is latched or not
latched.)
OD1 (OVF) = Over-voltage Flag.
OD0 (FAULT) = This flag reports a fault and is reset by a read
