REGISTERS
DESCRIPTIONS
Input Undervoltage Thresholds
(Registers 00h to 03h)
Input undervoltage thresholds (0.5V to 3.04V in 10mV increments or 1.0V to 5.5V in 20mV
increments). Each channel’s range is selected with register 08h.
Input Overvoltage Thresholds
(Registers 04h to 07h)
Input overvoltage thresholds (0.5V to 3.04V in 10mV increments or 1.0V to 5.5V in 20mV
increments). Each channel’s range is selected with register 08h.
Tracking/Sequencing Modes
Selects if outputs are to be sequenced or tracked. Sequencing/tracking modes are defined
by 4 bits for each OUT voltage of register 0Bh and 0Ch (see the Track/Sequence section).
Tracking/Sequencing
Power-Up/Down Slew Rate
Selectable output slew rate for power-up/down mode. Selected slew is overwritten during
tracking faults. Power-up/down slew rate is selected by bit [6:7] of register 12h.
Power-Up Delay Period
Power-up sequencing delay. Selects delay time for sequencing each supply.
Programmable delays are selected with bit [5:7] of register 0Fh.
Power-Down Sequence/Track
Behavior
Selectable power-down operation. Chooses if output voltages should be brought down in
the reverse sequence from power-up mode selections or if power supplies should be
simultaneously fast powered down (selected with bit 7 register 13h).
OUT Pulldown Enable
Selects if OUT_ should be internally pulled to GND when in fast shutdown or tracking fault
mode (selected with bit [6:3] register 13h).
Single/Multiple Device Application
Selects if the device will be used alone or in a master/slave application. If a single
application, the device can be operated in mixed sequencing/tracking modes. If multi-
device application, the device can be operated in tracking mode only (selected with bit
[7:6] register 09h).
00: single device 11: master device 01 or 10: slave device
Overcurrent Threshold
Selects IN_-to-OUT_ threshold voltage for overcurrent monitoring for each channel (register 0Dh).
Power-Good Threshold
Selects IN_-to-OUT_ threshold voltage for power-good monitoring for each channel
(register 10h).
Overcurrent Assert Select
Selects which overcurrent monitors will assert the OC output (selected by bit [5:2] of reg. 0Eh).
Overcurrent Filter Period
Selects the filter time for the overcurrent monitors. OC will not assert until the overcurrent
condition has existed longer than the selected filter period (selected by bit [7:6] of reg. 0Eh).
Fault Timeout Period
Selects the timeout period for sequencing/tracking completion. If sequencing/tracking
operation is not complete before the fault timeout period, a FAULT alert will be signaled
and all supplies will be powered down (selected by bit [7:4] of reg. 0Ah).
Fault Behavior
Selects how the device should operate during faults. Options include latch-off after fault or
autoretry after fault. Autoretry delay is selectable (selected by bit 5 of reg. 09h).
Reset Assert Select
Selects which OUT detectors will assert the RESET output (selected by bit [7:4] of reg. 11h).
Reset Timeout Period Select
Selects the reset timeout period (selected by bit [3:1] of reg. 11h).
Enable the Part with I
2C Interface
Bit 0 and bit 1 of register 09h allows a micro to turn the MAX6876 on/off with the I
2C
interface. While 09h[1] is 0, the part will ignore any enable command from I
2C. If 09h[1] is
set to 1, then 09h[0] has to be 1 to enable the part to power on.
