DESCRIPTION
IN2 Overvoltage Threshold
V TH = 1.0 + n x 20mV (if R08[6] = 0)
05h
25h
[7:0]
V TH = 0.5 + n x 10mV (if R08[6] = 1)
where n is the register content decimal representation. Note that V TH ranges
must be 1V to 5.5V and 0.5V to 3.05V, respectively.
IN3 Overvoltage Threshold
V TH = 1.0 + n x 20mV (if R08[5] = 0)
06h
26h
[7:0]
V TH = 0.5 + n x 10mV (if R08[5] = 1)
where n is the register content decimal representation. Note that V TH ranges
must be 1V to 5.5V and 0.5V to 3.05V, respectively.
IN4 Overvoltage Threshold
V TH = 1.0 + n x 20mV (if R08[4] = 0)
07h
27h
[7:0]
V TH = 0.5 + n x 10mV (if R08[4] = 1)
where n is the register content decimal representation. Note that V TH ranges
must be 1V to 5.5V and 0.5V to 3.05V, respectively.
Bit 7 — If 0, 20mV steps in V TH setting for IN1
If 1, 10mV steps in V TH setting for IN1
Bit 6 — If 0, 20mV steps in V TH setting for IN2
If 1, 10mV steps in V TH setting for IN2
08h
28h
[7:4]
Bit 5 — If 0, 20mV steps in V TH setting for IN3
If 1, 10mV steps in V TH setting for IN3
Bit 4 — If 0, 20mV steps in V TH setting for IN4
If 1, 10mV steps in V TH setting for IN4
Manual Reset Input ( MR )
The manual reset ( MR ) input initiates a reset condition.
MR is internally pulled up to ABP through a 100k ?
resistor. When MR is low, RESET remains low for the
selected reset timeout period after MR transitions from
low to high (see the Reset Output ( RESET ) section).
Margin Input ( MARGIN )
MARGIN allows system-level testing while power sup-
plies exceed the normal ranges. Drive MARGIN low
before varying system voltages below/above the select-
ed threshold without signaling an error. MARGIN makes
it possible to vary the supplies without a need to repro-
gram the IN_ or PG_ thresholds and prevents
tracker/sequencer alerts or faults. Drive MARGIN high
or leave it floating for normal operating mode.
ENABLE
Drive logic ENABLE input high to initiate voltage track-
ing/sequencing during power-up operation. Drive logic
ENABLE low to initiate tracking/sequencing power-down
operation. When ENABLE is not used, connect to ABP.
When the MAX6876 is configured to use the I 2 C on/off
command, a valid I 2 C signal must be received before
the device begins the power-up tracking/sequencing
routine. The internal enable logic is an AND function of
the ENABLE logic, the TRKEN logic, and the I 2 C con-
trol/command logic (Figure 7). When all three AND gate
input variables are true (and the monitored IN/OUT volt-
ages meet their required thresholds), turn-on is allowed.
When any AND input variable becomes false, the turn-
off cycle (track/sequence down) begins immediately.
Drive ENABLE and TRKEN high if only the I 2 C com-
mand is to be used to turn on/off the device. The detec-
tors monitoring IN_ and OUT_ voltages, and
overcurrent conditions have a higher priority after a
power-on routine has been initiated by the internal
enable logic. If a fault occurs during the power-up
cycle, the device is powered down immediately, inde-
pendent of ENABLE, TRKEN, and the I 2 C shutdown
