FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Previous Address SOA[2:0] = 010
The data in bit OD3 contain the programmed over-current
high detection level (refer to Table 12 ), and the data in bits
OD2, OD1, and OD0 contain the programmed over-current
low detection levels (refer to Table 11 ).
Table 17. Fault Register
Previous Address SOA[2:0] =100
The returned data contain the programmed values in the
DICR.

? SOA3 = 1. The returned data contain the programmed
values in the WDR. Bit OD2 (WDTO) reflects the status of
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
operation.
the watchdog circuitry. If WDTO bit is Logic [1], the
watchdog has timed out and the device is in Fail-safe
mode. If WDTO is Logic [0], the device is in Normal mode
(assuming device is powered and not in the Sleep mode),
with the watchdog either enabled or disabled.
Previous Address SOA[2:0] =110
? SOA3 = 0. OD2, OD1, and OD0 return the state of the IN,
FSI, and WAKE pins, respectively ( Table 18 ).
Table 18. Pin Register
Note The FS pin reports a fault and is reset by a new Switch-ON
command (via SPI or direct input IN).

The data returned in bits OD1 and OD0 are current values
Bit OD2 reports when the over-current detection timeout
feature is active. OD3 reports whether the open load circuitry
is active.
? SOA3 = 1. The returned data contains the programmed
values in the UOVR register. Bit OD1 reflects the state of
the under-voltage protection, while bit OD0 reflects the
state of the over-voltage protection (refer to Table 16 ).
Previous Address SOA[2:0] = 111
Null Data. No previous register Read Back command
received, so bits OD2, OD1, and OD0 are null, or 000.
