Status [D4] bit shows ILIM status. It is latched to 1 if the ILIM status is triggered. The latch can be removed

by the REFRESH bit in REG00.

Status [D3] bit shows the real-time operation status for power stage. It is set to 1 when the power stage is

operating normal. It will be latched to 0 in the following cases:



Hiccup mode (pre-soft-start completion)



Disabled states (EN/SD/I2C_ON = low)



Thermal shutdown



Initial startup sequence

Status [D1] bit shows overtemperature (OT) status. It is latched to 1 if the OT fault is triggered. The latch

can be removed by the REFRESH bit in REG00. DIO8833 shuts down once OT fault occur.

Status [D0] bit shows overtemperature-warning (OTW) status. It is latched to 1 if the OTW is triggered. The

latch can be removed by the REFRESH bit in REG00.

As mentioned above, certain status bits remain latched high upon detection of their corresponding events.

To clear these latched bits, write 1 to the REFRESH bit (Reg00[D1]). This triggers a one-time refresh of all

latched status bits in the status register. The REFRESH bit automatically returns to 0 after the operation

completes.
