WATCHDOG_FAULT

0: No Fault

1: Watchdog Fault

Watchdog Timeout Fault

This bit is latching. If Watchdog is enabled and

watchdog timer times out, then this bit is set high.

This bit is not cleared when read. The watchdog

timer is cleared with a watchdog read or by disabling

the watchdog timer.

VOUT_FAULT

0: No Fault

1: VOUT Fault

Output Hiccup Mode Fault

This bit is latching. Read this bit to clear the value

back to 0. If the VOUT enters hiccup state because

current exceeds the Constant Current Mode, then

this bit gets set.

This register will always be set during hiccup mode

when VOUT is off during the 3sec restart time and

converter is in the HICCUP state. After it exits this

state, a read clears this bit.

VIN_UV_FLT

0: No Fault

1: VIN UV Fault

VIN UV Fault

This bit is latching. If VIN falls below the

VIN_UV_OFFSET Voltage specified in the

VIN_UV_OFFSET Register (Reg 0x0F, Bits 7:5), this

bit is set to 1.

When the input voltage is above the

VIN_UV_OFFSET voltage, a read will clear this fault

bit.

VOUT_OV

0: No Fault

1: VOUT OV Fault

Vout Overvoltage Fault

Read to Clear latching bit

This bit will be set any time the Vout exceeds the OV

threshold for external or internal feedback. The

VOUT must be below the OV voltage and then a

read will clear this fault bit.

LIGHT_LOAD

0: No Fault

1: Converter off

Output Light Load State Latch

This bit is latching. This bit is set when the converter

has been disabled because of light load condition on

output and it entered the LL_DIS state. After the IC

exits the LL_DIS state, a read clears this bit.

VIN_OV

0: No Fault

1: VIN OV

VIN Overvoltage fault

This bit is latching. This bit is set any time VIN

exceeds the OV threshold when in the POWER ON

state. VIN must be below the OV voltage and then a

read clears this bit.

I2C_FAULT

0: No Fault

1: I2C Fault

If set to 1, I2C command did not finish correctly or

errors on I2C data
