D2h SET_FAULT_RESPONSE Read/Write 2
Word
BIT
Set by the Intersil defined register. Each of bits[9:2] controls page 60
HIC/LATCH pin the respective type of 8 fault condition’s response
as listed below. Bit = 1 or 0 sets the fault protection
response to be either Hiccup or Latch-off mode.
Bits [15:10]: Not used
Bit [9]: PLL_LOCK fault
Bit [8]: PLLCOMP_SHORT fault
Bit [7]: VOUT_OV fault
Bit [6]: VOUT_UV fault
Bit [5]: OC2_IPEAK fault
Bit [4]: OC_AVG fault
Bit [3]: OT_NTC_FAULT fault
Bit [2]: VIN_OV fault
Bit [1]: Not used
Bit [0]: Not used

Bit = 1 means Hiccup mode
Bit = 0 means Latch-off mode
06h
Intersil defined register. Set the output overvoltage page 61
fault threshold for the output voltage measured at
the FB pin.
Bits [7:3]: Not used
Bits [2:0]: Valid bits
01h
Intersil defined register. Set the output
page 62
undervoltage fault threshold for the output voltage
measured at the FB pin.
[7:3]: Not used; [2:0] Valid bits
07h
Intersil defined register. Set the constant current page 63
control threshold for the boost input current
measured at the IMON pin.
Bits [7:3]: Not used
Bits [2:0]: Valid bits
07h
Intersil defined register. Set the average overcurrent page 64
fault threshold for the boost input average current
measured at the IMON pin.
Bits [7:3]: Not used
Bits [2:0]: Valid bits
