vin_uv_lvl
(0x0B)
2.21mV per LSB
V
IN
Undervoltage Level: This is an alarm threshold for the input voltage. If enabled, the voltage falling below this level will trigger an alarm and an
SMBALERT.
vin_ov_lvl
(0x0C)
2.21mV per LSB
V
IN
Overvoltage Level: This is an alarm threshold for the input voltage. If enabled, the voltage rising above this level will trigger an alarm and an
SMBALERT.
vcap_uv_lvl
(0x0D)
1.476mV per LSB
V
CAP
Undervoltage Level: This is an alarm threshold for the capacitor stack voltage. If enabled, the voltage falling below this level will trigger an alarm and
an SMBALERT.
vcap_ov_lvl
(0x0E)
1.476mV per LSB
V
CAP
Overvoltage Level: This is an alarm threshold for the capacitor stack voltage. If enabled, the voltage rising above this level will trigger an alarm and
an SMBALERT.
vout_uv_lvl
(0x0F)
2.21mV per LSB
V
OUT
Undervoltage Level: This is an alarm threshold for the output voltage. If enabled, the voltage falling below this level will trigger an alarm and an
SMBALERT.
vout_ov_lvl
(0x10)
2.21mV per LSB
V
OUT
Overvoltage Level: This is an alarm threshold for the output voltage. If enabled, the voltage rising above this level will trigger an alarm and an
SMBALERT.
iin_oc_lvl
(0x11)
1.983µV/R
SNSI
per LSB
Input Overcurrent Level: This is an alarm threshold for the input current. If enabled, the current rising above this level will trigger an alarm and an
SMBALERT.
ichg_uc_lvl
(0x12)
1.983µV/R
SNSC
per LSB
Charge Undercurrent Level: This is an alarm threshold for the charge current. If enabled, the current falling below this level will trigger an alarm and an
SMBALERT.
dtemp_cold_lvl
(0x13)
Temperature = 0.028°C per LSB – 251.4°C
Die Temperature Cold Level: This is an alarm threshold for the die temperature. If enabled, the die temperature falling below this level will trigger an alarm
and an SMBALERT.
dtemp_hot_lvl
(0x14)
Temperature = 0.028°C per LSB – 251.4°C
Die Temperature Hot Level: This is an alarm threshold for the die temperature. If enabled, the die temperature rising above this level will trigger an alarm
and an SMBALERT.
esr_hi_lvl
(0x15)
R
SNSC
/64 per LSB
ESR High Level: This is an alarm threshold for the measured stack ESR. If enabled, a measurement of stack ESR exceeding this level will trigger an alarm
and an SMBALERT.
