NAME

PG/
RST
Power-Good Output, Open-Drain. PG_
RST
asserts high t
TIMEOUT
after all
OUT_ voltages exceed the V
TH_PG
thresholds.
15
15
10
FAULT
Tracking Fault Alert Output, Active Low, Open-Drain.
FAULT
asserts low if a
tracking failure is present for longer than the selected fault period or if
tracking voltages fail by more than ±250mV.
FAULT
asserts low if any OUT_
falls below the corresponding IN_ voltage.

OUT3
Channel 3 Monitored Output Voltage. Connect OUT3 to the source of an n-
channel FET. A fault condition activates a 100
pulldown to ground.

GATE3
Gate Drive for External n-Channel FET. An internal charge pump boosts
GATE3 to V
IN3
+ 5V to fully enhance the external n-channel FET when power-
up is complete.

OUT2
Channel 2 Monitored Output Voltage. Connect OUT2 to the source of an
n-channel FET. A fault condition activates a 100
pulldown to ground.

IN1
Supply Input Voltage. IN1, IN2, or IN3 must be greater than the internal
undervoltage lockout (V
ABP
= 2.7V) to enable the tracking or sequencing
functionality. Each IN_ input is simultaneously monitored by SET_ inputs to
ensure all supplies have stabilized before power-up is enabled. If IN_ is
connected to ground or left unconnected and SET_ is above 0.5V, then no-
sequencing control is performed on that channel. Each IN_ is internally
pulled down by a 100k
resistor.
