GPIO Data
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.
Voltage fault flag bits. Flags for each input signal when undervoltage or overvoltage
threshold is exceeded.
GPIO state data. Used to read back and control the state of each GPIO.
ADC input voltage range. Selects the voltage range of the monitored inputs.
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.
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.
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 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, FAULT1, and FAULT2 output configuration. Programs the functionality of the
RESET, FAULT1, and FAULT2 outputs, as well as which inputs they depend on.
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.
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.
Configure watchdog functionality for GPIO5 and GPIO6.
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.
