Register Summary (All Registers 8-Bits Wide)
Note:
This data sheet uses a specific convention for referring to bits within a particular address location. As an example, r15h[3:0]
refers to bits 3 through 0 in register with address 15 hexadecimal.

REGISTER
DESCRIPTION
ADC Conversion Results
(Registers r00h to r17h)
Input ADC conversion results. ADC writes directly to these registers during normal
operation. ADC input ranges (MON1–MON12) are selected with registers r0Fh to r11h.
Failed Line Flags
(Registers r18h to r19h)
Voltage fault flag bits. Flags for each input signal when undervoltage or overvoltage
threshold is exceeded.
Extended
GPIO Data
(Registers r1Ah to r1Bh)
GPIO state data. Used to read back and control the state of each GPIO.
ADC Range Selections
(Registers r0Fh to r11h)
ADC input voltage range. Selects the voltage range of the monitored inputs.
Fault Behavior
(Registers r47h to r4Ch)
Selects how the device should operate during faults. Options include latch-off or
autoretry after fault. The autoretry delay is selectable (r4Fh). Use registers r48h
through r4Ch to select fault conditions that trigger a critical fault event.
GPIO Configuration
(Registers r1Ch to r1Eh)
General-purpose input/output configuration registers. GPIOs are configurable as a
manual-reset input, a margin disable input, a watchdog timer input and output, logic
inputs/outputs, fault-dependent outputs, or as the feedback/pulldown inputs (INS_) for
closed-loop tracking.
Overvoltage and
Undervoltage Thresholds
(Registers r23h to r46h)
Input overvoltage and undervoltage thresholds. ADC conversion results are compared
to overvoltage and undervoltage threshold values stored here. MON_ voltages
exceeding threshold values trigger a fault event.
Programmable Output
Configuration
(Registers r1Fh to r22h)
Programmable output configurations. Selectable output configurations include: active-
low or active-high, open-drain or push-pull outputs. EN_OUT1–EN_OUT6 are
configurable as charge-pump outputs and EN_OUT1–EN_OUT4 can be configured for
closed-loop tracking.
RESET
and Fault Outputs
(Registers r15h to r1Bh)
RESET
,
FAULT1
, and
FAULT2
output configuration. Programs the functionality of the
RESET
,
FAULT1
, and
FAULT2
outputs, as well as which inputs they depend on.
Sequencing-Mode
Configuration
(Registers r50h to r5Bh and
r5Eh to r63h)
Assign inputs and outputs for sequencing. Select sequence delays (20μs to 1.6s) with
registers r50h through r54h. Use register r54h to enable/disable the reverse sequence
bit for power-down operation.
Software Enable
and Margin
(Register r4Dh)
Use register r4Dh to set the
Software Enable
bit, to select early warning thresholds
and undervoltage/overvoltage, to enable/disable margining, and to enable/disable the
watchdog for independent/dependent mode.
Default and
EEPROM
Watchdog Functionality
(Register r55h)
Configure watchdog functionality for GPIO5 and GPIO6.
Fault Log Results
(Registers r00h to r0Eh)
ADC conversion results and failed-line flags at the time of a fault. These values are
recorded by the fault event logger at the time of a critical fault.
EEPROM
User EEPROM (Registers
r9Ch to rFFh)
User-available EEPROM
