Channel 3 Monitored Output Voltage. Connect OUT3 to the source

of an n-channel FET. A fault condition activates a 100

Ω pulldown to

ground.

IN1

Supply Input Voltage. IN1, IN2, or IN3 must be greater than 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

Ω resistor.
