DESCRIPTION
7
CU
Cascade U
Indicates the device is an ISL9217. This bit is set in hardware and cannot be changed.
6
CL
Cascade L
Indicates the device is an ISL9216. This bit is set in hardware and cannot be changed.
5
SA
Reserved for ISL9208 devices.
4
WKUP
Wake-up Pin Status
This bit is set and reset by hardware.
When ‘WKPOL’ is HIGH,
’WKUP’ HIGH = WKUP pin > Threshold voltage
‘WKUP’ LOW = WKUP pin < Threshold voltage
When ‘WKPOL’ is LOW
’WKUP’ HIGH = WKUP pin < Threshold voltage
‘WKUP’ LOW = WKUP pin > Threshold voltage

XOT
Ext Over-temp
(ISL9216 only)
This bit is set to “1” when the external thermistor indicates an over-temperature condition. If the temperature condition
has cleared, this bit is reset when the register is read.
4
IOT
Int Over-temp
This bit is set to “1” when the internal thermistor indicates an over-temperature condition. If the temperature condition
has cleared, this bit is reset when the register is read.
3
LDFAIL
Load Fail (VMON)
(ISL9216 only)
When the function is enabled, this bit is set to “1” by hardware when a discharge overcurrent or short circuit condition
occurs and the load remains heavy. When the load fail condition is cleared or under a light load, the bit is reset when the
register is read.
2
DSC
Short Circuit
(ISL9216 only)
This bit is set by hardware when a short circuit condition occurs during discharge. When the discharge short circuit
condition is removed, the bit is reset when the register is read.
1
DOC
Discharge OC
(ISL9216 only)
This bit is set by hardware when an overcurrent condition occurs during discharge. When the discharge overcurrent
condition is removed, the bit is reset when the register is read.
0
COC
Charge OC
(ISL9216 only)
This bit is set by hardware when an overcurrent condition occurs during charge. When the charge overcurrent condition
is removed, the bit is reset when the register is read.
