PG/
RST
Power-Good Output, Open-Drain. PG_
RST asserts high tTIMEOUT
after all OUT_ voltages exceed the VTH_PG thresholds.

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.
17

—
GATE3
Gate Drive for External n-Channel FET. An internal charge pump
boosts GATE3 to VIN3 + 5V to fully enhance the external n-channel
FET when power-up is complete.
18
11
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.

GATE2
Gate Drive for External n-Channel FET. An internal charge pump
boosts GATE2 to VIN2 + 5V to fully enhance the external n-channel
FET when power-up is complete.

OUT1
Channel 1 Monitored Output Voltage. Connect OUT1 to the source
of an n-channel FET. A fault condition activates a 100 pulldown to
ground.

GATE1
Gate Drive for External n-Channel FET. An internal charge pump
boosts GATE1 to VIN1 + 5V to fully enhance the external n-channel
FET when power-up is complete.

IN1
Supply Input Voltage. IN1, IN2, or IN3 must be greater than the
internal undervoltage lockout (VABP = 2.7V) to enable the
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.
EP
Exposed Paddle. Connect exposed paddle to ground.
