DETAILED REGISTER DESCRIPTIONS
FAULT REGISTERS
Register 0x04 to Register 0x07 are latched fault registers. In these registers, flags are not reset when the fault disappears. Flags are cleared
only by a register read (provided that the fault no longer persists). Note that latched bits are clocked on a low-to-high transition only. Also
note that these register bits are cleared when read via the I2C interface unless the fault is still present. It is recommended that the latched
fault register be read again after the faults disappear to ensure that the register is reset.

7
Power supply
R
1 = power supply is off. All PWM outputs are disabled. This bit
stays high until the power supply is restarted.
None
6
OrFET
R
1 = OrFET control signal at the GATE pin (Pin 16) is off.
0x30
5
PGOOD1 fault
R
1 = Power-Good 1 fault. At least one of the following flags has been
set: soft start flag, CS1 fast OCP, CS1 accurate OCP, CS2 accurate OCP,
UVP, local OVP, load OVP, or OrFET (GATE pin). These flags can be
masked using Register 0x7B.
0x2D
None
4
PGOOD2 fault
R
1 = Power-Good 2 fault. At least one of the following flags has been
set: soft start flag, CS1 fast OCP, CS1 accurate OCP, CS2 accurate OCP,
UVP, local OVP, load OVP, or OrFET (GATE pin). These flags can be
masked using Register 0x7C.
The following flags can also set PGOOD2, either unconditionally
or based on the flag response, as defined in Register 0x2D[3] (see
Table 45): voltage continuity, OrFET disable, ACSNS, external flag
(FLAGIN pin), and OTP.
0x2D
None
3
SR off
R
SR1 and SR2 synchronous rectifiers are disabled. This flag is set
when one of the following cases is true:
None
SR1 and SR2 are disabled by the user.
0x5D
The load current has fallen below the threshold in Register 0x3B.
0x3B
A flag has been set that is configured to disable the synchronous
rectifiers.
0x08 to
0x0D
2
CS1 fast OCP
R
CS1 current is above its fast overcurrent protection limit. There is a
1.2 V threshold on the CS1 pin. Fast OCP is a comparator.
Programmable
1
CS1 accurate OCP
R
CS1 current is above its accurate overcurrent protection limit.
0x22
Programmable
0
CS2 accurate OCP
R
CS2 current is above its accurate overcurrent protection limit.
0x26
Programmable

Voltage
continuity
R
Voltage differential between VS1 and VS2 pins or between VS2
and VS3± pins is outside limits. Either (VS1 − VS2) > 50 mV or
(VS2 − VS3) > 50 mV at the pins.
Programmable
6
UVP
R
VS1 is below its undervoltage limit.
0x34
Programmable
5
CS2 reverse
current
R
Reverse voltage across the CS2± pins is above limit. This is the
OrFET reverse voltage.
0x30
Programmable
4
VDD UV
R
VDD is below limit.
Immediate shutdown
3
VCORE OV
R
2.5 V VCORE is above limit.
Immediate shutdown
2
VDD OV
R
VDD is above limit. The I2C interface stays functional, but a PSON
toggle is required to restart the power supply.
0x0E
Programmable

Load OVP
R
VS2 or VS3± is above its overvoltage limit.
0x33
Programmable
0
Local OVP
R
VS1 is above its overvoltage limit.
0x32
Programmable
