Functional Pin Description
GATE
This is the Gate Drive output of the external N-Channel
MOSFET generated by the IC internal charge pump. Gate
turn on time is typically 1ms.
VIN
Input bias pin connected to the sourcing supply side (ORing
MOSFET Source). Also serves as the sense pin to
determine the sourcing supply voltage. The ORing MOSFET
will be turned off when VIN becomes lower than VOUT by a
value more than the externally set threshold.
VOUT
Connected to the Load side (ORing MOSFET Drain). This is
the VOUT sense pin connected to the load. This is the
common connection point for multiple paralleled supplies.
VOUT is compared to VIN to determine when the ORing
FET has to be turned off.
HVREF
Low side of the internal IC High Voltage Reference used by
internal circuitry, also available as an external pin for
additional external capacitor connection.
COMP
This is the high side connection for the HS Comparator trip
level setting (VTH(HS)). A resistor R1 connected between
COMP and VOUT along with resistor R2 provides adjustable
VOUT-VIN trip level (0 to 5V). This provides flexibility to
externally set the desired level depending on particular
system requirement.
VSET
Low side connection for the HS Comparator trip level setting
A second resistor R2 connected between VSET and COMP
provides adjustable “VIN - VOUT” level along with R1.
FAULT
Open-Drain pull-down FAULT Output with internal on chip
filtering (TFLT). The ISL6144 fault detection circuitry will pull
down this pin to GND as soon as it detects a fault. Different
types of faults and their detection mechanisms are
discussed in more detail in the Block Diagram Description
section.

Detailed Description
The ISL6144 and a suitably sized N-Channel power
MOSFET(s) increases power distribution efficiency and
availability when replacing a power ORing diode in high current
applications. Refer to the Application Consideration section for
power saving when using ISL6144 with an N-channel ORing
MOSFET compared to a typical ORing diode.
Functional Block Description
REG. AMPLIFIER - Slow (Quiet) Turn Off
A Hysteretic Regulating (HR) Amplifier is used for a Quiet/
Slow turn off mechanism. This slow turn off is initiated when
the sourcing power supply is turned off slowly for system
diagnostics. Under normal operating conditions as VOUT
pulls up to 20mV below VIN (VIN-20mV > VOUT), the HR
Amplifier regulates the gate voltage to keep the 20mV
(VFWD_HR) forward voltage drop across the ORing MOSFET
(Vs-Vd). This will continue until the load current exceeds the
MOSFET ability to deliver the current with Vsd of 20mV. In
this case Gate will be charged to the full charge pump
voltage (VGQP) to fully enhance the MOSFET. At this point
the MOSFET will be fully enhanced and behave as a
constant resistor valued at the rDS(ON). Once VIN starts to
drop below VOUT, regulation cannot be maintained and the
output of the HR Amp is pulled high and the gate is pulled
down to VIN slowly in less than a 100s. As a result, the
ORing FET is turned off, avoiding reverse current as well as
voltage and current stresses on supply components.
